  • The Evolution of the Horse
    BY LES SELLNOW he evolution of the horse from a tiny, four-toed an imal, T perhaps no more than one foot tall, to the variety of equines in existence today, is one of the wonders of nature. During that process of change, the horse evolved over many thousands of years from an animal that predators hunted for food to an animal that became a servant and friend for mankind. Today’s horses are designed to do one of two things— pull a load with their shoulders or carry riders on their backs. The type of horses utilized for these respective tasks varies a good deal; one is large and pon d erous and the other is lighter-boned with less mu s cle mass. Even within these two types, there are significant differences. For example, the conformation of a roping or cutting This first article of a 12-part series on equine anatomy and horse is different from that of the American Saddle- physiology discusses basic terminology, the horse’s largest bred.

  • Stepwise Standardized Approach to the Basic Ultrasound Examination
    STEPWISE STANDARDIZED APPROACH TO THE BASIC ULTRASOUND 14 EXAMINATION OF THE FEMALE PELVIS INTRODUCTION The stepwise standardized approach to the basic ultrasound examination of the female pelvis applies a structured and standardized method of ultrasound examination which is simple to learn and complies with existing guidelines for the performance of the gynecologic examination (1). This stepwise approach is comprised of five steps that are geared towards the identification of pelvic abnormalities and comprise the basic gynecologic ultrasound examination. The five steps are designed to assess the bladder, uterus and cervix, the cul-de-sac, the adnexae and surrounding structures. This chapter describes the sonographic approach that is employed for each of the five steps and uses images and video clips to illustrate each step. Evaluation of the female pelvis by ultrasound is best achieved by the transvaginal approach, using a transvaginal transducer. This chapter will focus on this approach. When the transvaginal approach is not feasible, the transrectal approach is preferred and is usually well tolerated. The presence of a large pelvic mass that expands outside of the range of the transvaginal transducer necessitates a complementary abdominal approach for comprehensive assessment. STEP ONE: PREPARING AND INTRODUCING THE TRANSVAGINAL TRANSDUCER The transvaginal transducer is an endocavitary transducer that is designed to fit into small spaces. It is shaped like a long cylinder with a handle and has a small footprint at its tip that transmits and receives sound waves from the end of the transducer (Figure 14.1). The frequency range of a transvaginal transducer is typically in the 5-12 MHZ and given this high resolution, effective imaging to a 7-10 cm range can generally be achieved.

  • Anatomy and Medical Terminology] Msc
    Lecture_2 [ANATOMY AND MEDICAL TERMINOLOGY] MSC. NABAA SALAH Directional term: In general, directional terms are grouped in pairs of opposites based on the standard anatomical position. Superior and Inferior. Superior means above, inferior means below. The elbow is superior (above) to the hand. The foot is inferior (below) to the knee. Anterior and Posterior. Anterior means toward the front (chest side) of the body, For example, the abdominal muscles are anterior to the spine. Ventral is similar to anterior; it means toward the abdomen. Posterior means toward the back, the spine is posterior to the abdominal muscles. The term dorsal has a similar meaning as posterior. Median, Medial and Lateral. Median: At the midline of the body. The nose is a median structure. Medial means toward the midline of the body, the big toe is medial to the little toe. Lateral means away from the midline, the little toe is lateral to the big toe. Proximal and Distal Proximal means closest to the point of origin or trunk of the body, the shoulder is proximal to the elbow. Distal means farthest away, the elbow is distal to the shoulder. Proximal and distal are often used when describing arms and legs. Superficial and Deep. Superficial means toward the body surface, the skin is superficial to the muscles. Page 1 Lecture_2 [ANATOMY AND MEDICAL TERMINOLOGY] MSC. NABAA SALAH Deep means farthest from the body surface, the abdominal muscles are deep to the skin. Other directional terms: . Intermediate – means between—your hearts is intermediate to your lungs. Caudal – at or near the tail or posterior end of the body.

  • The Language of Anatomy the Medial Line the Medial Line Is the Central
    The Language of Anatomy The Medial Line The medial line is the central axis of the figure, dividing the body vertically into equal right and left haves. (In medical terminology, it is referred to as the midsagittal plane.) On the front (anterior) side of the body, the medial line travels straight down through the cranium, breastbone, navel, and pubic bone, continuing between the legs down to the ground. On the back (posterior) side, the medial line goes through the cranium, follows the spine, and again continues down to the ground between the legs. The central axis of the body is a valuable landmark because it helps you accurately assess the figure’s position, as when there is a noticeable tilt to the torso or a twisting action in the torso. In action poses, the central axis generally travels down through the leg that is more stable or that is positioned in a way that continues the action of the pose in a more sweeping gesture. Anatomical Planes The anatomical planes are three planes or reference that divide the body vertically and horizontally while it is in the anatomical position. Think of these imaginary planes as thin sheets of transparent glass, perpendicular to one another, that slice through the body, creating three different dimensions. Specific kinds of movement can only occur within certain planes. Sagittal Plane The sagittal plane divides the body vertically into equal right and left halves. This plane is also referred to as the midsagittal plane because it is on the midline of the body. Movements within the sagittal plane are flexion and extension – forward and backward movements of the head, spine, and limbs.

  • An Exploration of Spatial Radiomic Features in Pulmonary Sarcoidosis
    An Exploration of Spatial Radiomic Features in Pulmonary Sarcoidosis Sarah M. Ryan Tasha Fingerlin, Nabeel Hamzeh Lisa Maier Nichole Carlson June 28, 2018 Abstract Sarcoidosis is a rare, multi-systemic, inflammatory disease, primarily affecting the lungs. High-resolution computed tomography (CT) scans are used to clinically characterize pulmonary sarcoidosis. In the medical imag- ing field, there is growing recognition to switch from visual examination of CT images to more rapid, objective assessments of the abnormalities. In this work, we explore the usefulness of various objective measures of spa- tial heterogeneity|fractal dimension, Moran's I, and Geary's C |for dis- tinguishing between abnormal sarcoidosis and normal lung parenchyma. CT data for N=58 sarcoidosis subjects enrolled at National Jewish Health were obtained from the GRADS study. CT data for N=101 control patients were obtained from the COPDGene study. Radiomic measures were computed for each two-dimensional slice of a given scan, in the axial, coronal, and sagittal planes. Functional regression was applied to identify lung regions where CT nodules tend to proliferate. Moran's I, Geary's C and fractal dimension significantly differentiate between subjects with and without sarcoidosis throughout the majority of the lung, with disease abnormalities most apparent in the top axial, mid- dle coronal, and outer sagittal regions. A trend appeared across Scadding stages, with CT scans from patients with Scadding stages I and III ap- pearing the healthiest, and Scadding stage IV appearing the least healthy. The radiomic measures and techniques presented herein successfully characterize CT images in sarcoidosis by objectively and efficiently ap- proximating what we know about the pathology of sarcoidosis.

  • Day 1 Terminology & External/Internal Anatomy
    Day 1 Terminology & External/Internal Anatomy: Planes of Section & Directional Terms Position your cat on its back or side in the dissection tray. Use the following figures to locate important anatomical directions on the cat. These will be used throughout the lab in the directions for dissection Many terms for direction are the same in comparative and human anatomy, but there are certain differences occasioned by our upright posture. A structure toward the head end of a quadruped is described as cranial (or cephalad); one toward the tail, as caudal. A structure toward the back of a quadruped is dorsal, one toward the belly is ventral. Other terms for direction are used in the same way in all animals. Lateral refers to the side of the body; medial to a position toward the midline. Median is used for a structure in the midline. Distal refers to a part of some organ, such as appendage, that is farthest removed from the point of reference, such as the appendage’s point of attachment; proximal is the point nearest to the point of reference. A superficial structure lies upon another one and closer to the body surface, a deep one lies beneath others and farther from the body surface. Left and right are self-evident, but it should be emphasized that in anatomical directions, they always pertain to the specimen’s left or right, regardless of the way the specimen is viewed by the observer. The body of a specimen is frequently cut in various planes to obtain views of internal organs. A longitudinal, vertical section from dorsal to ventral that passes through the median longitudinal axis of the body is a sagittal section.

    - / I. Anatomical Positions, Directions, and Planes A. Anatomi cal Position - Standing, arms hanging, palms forward. Despite definition, the term also appli sittin,ge See diagram below. - B. Planes of the Body - A plane is a surface in which if any two points are taken, a straight line that is drawn to join these two points lies wholly within that plane or surface. Sagittal or Median Plane - A vertical plane running from front to back (Ante:;-Posterior) dividing the body into right and left parts. If the plane - divides the body into equal right and left parts by running through the middle of the breast bone (sternum) it is sometimes called the midsagittal or cardinal- sagittal plane. D. Median Plane of an Extremity - A plane running lengthwise through an extremity from front to back. This plane must pass through the third finger of - the hand or second toe of the foot. It is used as a reference nlane to movements that involve spreading the toes or fingers (except thumb) apartor moving them together. - E. Transverse Plane - A plane that divides the body or limbs into upper and lower parts, in relation to gravity and the anatomical position. F. Frontal or Coronal Plane - A plane dividing the body into an anterior and a posterior (ventral and dorsal) portion. Diagrams of Anatomical Reference Planes G. Anterior - Towards the front. Anatomists and zoologists differ in interpreting the two terms immediately above. When considering a four-legged animal, the zoolo- gists refer to the head as anterior, the tail posterior, the animal back as dorsal and under or belly side as ventral.
