Raj Dept. of ENT and Head and Neck Surgery, Maulana Azad Medical College and associated, L. N. Hospital, New Delhi - 110002, India. ABSTRACT Osteomas are benign, bone-forming tumours located within bones or developing on them. In the head and neck region they are commonly seen in the frontoethmoidal region. Occipital osteomas are very rare tumours. They are often asymptomatic and are incidentally found on radiological investigations. The main clinical symptom is headache of varying intensity and quality, though some patients may complain of dizziness in cases of large tumours. We describe here a case of occipital osteoma in a female, arising from the inner table. It was asymptomatic and osteoma was removed for cosmetic purpose. CT scan is a must to confirm the diagnosis, the involvement of the inner table as well as to look for any intracranial extent of the osteoma. KEY WORDS Osteoma, occipital bone.

A careful search of the English literature failed to reveal any previously reported case of occipital osteoma. Most often they are localized on sutures. Except for cortical lesions that are seen initially as cosmetic deformities, these tumours are usually unsuspected roentgenographic findings. The main clinical symptom is headache of varying intensity and quality, and in most cases not proportional to the size of the osteoma, which ranges from the size of a pepper bean to the size of a child’s head. In addition to headache, there can be sensitivity to pressure in the region of the frontal sinus or dizziness. Treatment is indicated for symptomatic osteomas.

ABSTRACT A case report of recurrent appendicitis, 40 years after appendectomy is presented. In the present case, we failed to diagnose stump appendicitis preoperatively due to the existence of the lipohyperplasia of the ileocecal valve which showed features of ileocolic intussusception causing right lower abdominal pain and nausea. Inflammation of the appendiceal stump after appendectomy is a rare complication, but in the assessment of patients with lower quadrant abdominal pain who have previously undergone appendectomies, stump appendicitis should be considered.

  • What Can I Learn from a Skull? Animal Skulls Have Evolved for Millions of Years to Protect Vertebrate’S Brains and Sensory Organs
    What Can I Learn From a Skull? Animal skulls have evolved for millions of years to protect vertebrate’s brains and sensory organs. Many of an animal’s dietary and social patterns can be deduced by examining its skull and teeth. HERBIVORE OMNIVORE CARNIVORE White-tailed Deer Virginia Opossum Coyote (Odocoileus virginianus) (Didelphis virginiana) (Canis latrans) TEETH SHOW DIET . The hardest and longest-lasting bone in the body is tooth enamel. The most common fossils are teeth, followed by jaws. Unlike other animals, mammals have only two sets of teeth, the first (often called ‘milk teeth’) erupts after birth. After puberty, a larger set, with more and bigger teeth to fill larger jawbones, emerges. There are four different types of teeth – • Incisors are the front teeth, used for cutting and grasping. • Canines are next to incisors and are used for tearing. • Premolars , located behind the canines, have sharp edges for crushing food. • Molars , the very back teeth, are broad, flat grinders. Generally, herbivores have large incisors to nip vegetation and premolars and molars to grind it into food; very few have canines. Carnivores, who eat meat, generally have small incisors, very large canines and sharp premolars and molars. Omnivores eat almost everything and their teeth reflect their Lakeside Nature Center 4701 E Gregory, KCMO 64132 816-513-8960 www.lakesidenaturecenter.org preferences; they have all four types of teeth. In fact, if you’d like to see an excellent example of an omnivore’s teeth, look in the mirror. EYE PLACEMENT IDENTIFIES PREDATORS . Carnivores generally have large eyes, placed so that the eyes look forward and the areas of vision of the two eyes overlap.

  • Implications to Occipital Headache
    The Journal of Neuroscience, March 6, 2019 • 39(10):1867–1880 • 1867 Neurobiology of Disease Non-Trigeminal Nociceptive Innervation of the Posterior Dura: Implications to Occipital Headache X Rodrigo Noseda, Agustin Melo-Carrillo, Rony-Reuven Nir, Andrew M. Strassman, and XRami Burstein Department of Anesthesia, Critical Care and Pain Medicine, Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, Massachusetts 02115 Current understanding of the origin of occipital headache falls short of distinguishing between cause and effect. Most preclinical studies involving trigeminovascular neurons sample neurons that are responsive to stimulation of dural areas in the anterior 2/3 of the cranium and the periorbital skin. Hypothesizing that occipital headache may involve activation of meningeal nociceptors that innervate the posterior 1⁄3 of the dura, we sought to map the origin and course of meningeal nociceptors that innervate the posterior dura overlying the cerebellum. Using AAV-GFP tracing and single-unit recording techniques in male rats, we found that neurons in C2–C3 DRGs innervate the dura of the posterior fossa; that nearly half originate in DRG neurons containing CGRP and TRPV1; that nerve bundles traverse suboccipital muscles before entering the cranium through bony canals and large foramens; that central neurons receiving nociceptive information from the posterior dura are located in C2–C4 spinal cord and that their cutaneous and muscle receptive fields are found around the ears, occipital skin and neck muscles; and that administration of inflammatory mediators to their dural receptive field, sensitize their responses to stimulation of the posterior dura, peri-occipital skin and neck muscles. These findings lend rationale for the common practice of attempting to alleviate migraine headaches by targeting the greater and lesser occipital nerves with anesthetics.

  • Biomechanics of Temporo-Parietal Skull Fracture Narayan Yoganandan *, Frank A
    Clinical Biomechanics 19 (2004) 225–239 www.elsevier.com/locate/clinbiomech Review Biomechanics of temporo-parietal skull fracture Narayan Yoganandan *, Frank A. Pintar Department of Neurosurgery, Medical College of Wisconsin, 9200 West Wisconsin Avenue, Milwaukee, WI 53226, USA Received 16 December 2003; accepted 16 December 2003 Abstract This paper presents an analysis of research on the biomechanics of head injury with an emphasis on the tolerance of the skull to lateral impacts. The anatomy of this region of the skull is briefly described from a biomechanical perspective. Human cadaver investigations using unembalmed and embalmed and intact and isolated specimens subjected to static and various types of dynamic loading (e.g., drop, impactor) are described. Fracture tolerances in the form of biomechanical variables such as peak force, peak acceleration, and head injury criteria are used in the presentation. Lateral impact data are compared, where possible, with other regions of the cranial vault (e.g., frontal and occipital bones) to provide a perspective on relative variations between different anatomic regions of the human skull. The importance of using appropriate instrumentation to derive injury metrics is underscored to guide future experiments. Relevance A unique advantage of human cadaver tests is the ability to obtain fundamental data for delineating the biomechanics of the structure and establishing tolerance limits. Force–deflection curves and acceleration time histories are used to derive secondary variables such as head injury criteria. These parameters have direct application in safety engineering, for example, in designing vehicular interiors for occupant protection. Differences in regional biomechanical tolerances of the human head have implications in clinical and biomechanical applications.

    6. The Pharynx The pharynx, which forms the upper part of the digestive tract, consists of three parts: the nasopharynx, the oropharynx and the laryngopharynx. The principle object of this dissection is to observe the pharyngeal constrictors that form the back wall of the vocal tract. Because the cadaver is lying face down, we will consider these muscles from the back. Figure 6.1 shows their location. stylopharyngeus suuperior phayngeal constrictor mandible medial hyoid bone phayngeal constrictor inferior phayngeal constrictor Figure 6.1. Posterior view of the muscles of the pharynx. Each of the three pharyngeal constrictors has a left and right part that interdigitate (join in fingerlike branches) in the midline, forming a raphe, or union. This raphe forms the back wall of the pharynx. The superior pharyngeal constrictor is largely in the nasopharynx. It has several origins (some texts regard it as more than one muscle) one of which is the medial pterygoid plate. It assists in the constriction of the nasopharynx, but has little role in speech production other than helping form a site against which the velum may be pulled when forming a velic closure. The medial pharyngeal constrictor, which originates on the greater horn of the hyoid bone, also has little function in speech. To some extent it can be considered as an elevator of the hyoid bone, but its most important role for speech is simply as the back wall of the vocal tract. The inferior pharyngeal constrictor also performs this function, but plays a more important role constricting the pharynx in the formation of pharyngeal consonants.

  • Lab Manual Axial Skeleton Atla
    1 PRE-LAB EXERCISES When studying the skeletal system, the bones are often sorted into two broad categories: the axial skeleton and the appendicular skeleton. This lab focuses on the axial skeleton, which consists of the bones that form the axis of the body. The axial skeleton includes bones in the skull, vertebrae, and thoracic cage, as well as the auditory ossicles and hyoid bone. In addition to learning about all the bones of the axial skeleton, it is also important to identify some significant bone markings. Bone markings can have many shapes, including holes, round or sharp projections, and shallow or deep valleys, among others. These markings on the bones serve many purposes, including forming attachments to other bones or muscles and allowing passage of a blood vessel or nerve. It is helpful to understand the meanings of some of the more common bone marking terms. Before we get started, look up the definitions of these common bone marking terms: Canal: Condyle: Facet: Fissure: Foramen: (see Module 10.18 Foramina of Skull) Fossa: Margin: Process: Throughout this exercise, you will notice bold terms. This is meant to focus your attention on these important words. Make sure you pay attention to any bold words and know how to explain their definitions and/or where they are located. Use the following modules to guide your exploration of the axial skeleton. As you explore these bones in Visible Body’s app, also locate the bones and bone markings on any available charts, models, or specimens. You may also find it helpful to palpate bones on yourself or make drawings of the bones with the bone markings labeled.
