Int. J. Morphol., 35(2):684-690, 2017. SUMMARY: The plantar aponeurosis (PA), which is a thickened layer of deep fascia located on the plantar surface of the foot, is comprised of three parts. There are differing opinions on its nomenclature since various authors use the terms PA and plantar fascia (PF) interchangeably. In addition, the variable classifications of its parts has led to confusion. In order to assess the nature of the PA, this study documented its morphology. Furthermore, a pilot histological analysis was conducted to examine whether the structure is an aponeurosis or fascia. This study comprised of a morphological analysis of the three parts of the PA by micro- and macro-dissection of 50 fetal and 50 adult cadaveric feet, respectively (total n=100). Furthermore, a pilot histological analysis was conducted on five fetuses (n=10) and five adults (n=10) (total n=20). In each foot, the histological analysis was conducted on the three parts of the plantar aponeurosis, i.e. the central, lateral, and medial at their calcaneal origin (total n=60). Fetuses: i) Morphology: In 66 % (33/50) of the specimens, the standard anatomical pattern was observed, viz.

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria.

  • The 4 Types of Tissues: Connective
    The 4 Types of Tissues: connective Connective Tissue General structure of CT cells are dispersed in a matrix matrix = a large amount of extracellular material produced by the CT cells and plays a major role in the functioning matrix component = ground substance often crisscrossed by protein fibers ground substance usually fluid, but it can also be mineralized and solid (bones) CTs = vast variety of forms, but typically 3 characteristic components: cells, large amounts of amorphous ground substance, and protein fibers. Connective Tissue GROUND SUBSTANCE In connective tissue, the ground substance is an amorphous gel-like substance surrounding the cells. In a tissue, cells are surrounded and supported by an extracellular matrix. Ground substance traditionally does not include fibers (collagen and elastic fibers), but does include all the other components of the extracellular matrix . The components of the ground substance vary depending on the tissue. Ground substance is primarily composed of water, glycosaminoglycans (most notably hyaluronan ), proteoglycans, and glycoproteins. Usually it is not visible on slides, because it is lost during the preparation process. Connective Tissue Functions of Connective Tissues Support and connect other tissues Protection (fibrous capsules and bones that protect delicate organs and, of course, the skeletal system). Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. Embryonic Connective Tissue All connective tissues derive from the mesodermal layer of the embryo . The first connective tissue to develop in the embryo is mesenchyme , the stem cell line from which all connective tissues are later derived.

  • Improving Flexibility
    IMPROVING FLEXIBILITY WHY IS FLEXIBILITY IMPORTANT? Flexibility is one of the main determinants of physical fitness, but it is often overlooked.[1] Maintaining range of motion in the body’s joints is important for basic functioning and may (along with other components of musculoskeletal fitness) be especially important to maintaining functionality in the setting of aging, injuries, and chronic illnesses.[2,3] While more research is still needed regarding the specific role of flexibility in overall physical fitness and health, most experts agree that structured flexibility exercises improve patients’ general health.[1-3] Small preliminary studies have suggested that flexibility may reduce arterial stiffening, which could theoretically reduce cardiovascular disease rates.[4] Stretching can also improve heart rate variability and reduce resting heart rate in patients. [5] Finally, flexibility exercises have consistently demonstrated benefits in short- and long- term balance performance.[6,7] Although previously suggested in expert guidelines, current research does not suggest that flexibility contributes to a decreased risk of injuries, falls, and chronic pain.[1] However, in practice, certain medical conditions such as osteoarthritis[8] and adhesive capsulitis[9] often warrant special attention to flexibility training to preserve or regain function. Despite these inconsistencies in current research on flexibility training, being able to move the body in a wider range of positions and movements gives us more options for accomplishing work, enjoying play, expressing ourselves, and finding comfort. When flexibility increases, the range of possibility increases. WHAT FACTORS AFFECT FLEXIBILITY? There are a variety of factors that contribute to a given person’s tendency to be more flexible or stiff.

This research aimed to study the histology of the digestive system of the watersnake (Enhydris enhydris). The digestive system taken was the esophagus, stomach, frontal small intestine and the back of the large intestine from three watersnakes. The samples were then made into histological preparations with hematoxylin-eosin (HE) staining and observed exploratively. The results showed that the digestive system of the watersnake was composed of layers of tissue, namely the mucosa, tunica submucosa, tunica muscularis, and serous tunica. Mucosal mucosa consisted of the lamina epithelium, lamina propria, and mucous lamina muscularis. The submucosal tunica consisted of connective tissue with blood vessels, lymph, and nerves. The muscular tunica was composed of circular muscles and elongated muscles. The serous tunica consisted of a thin layer of connective tissue that was covered by a thin layer of the mesothelium (mesothelium). The histological structure of the snake digestive system is not much different from the reptile digestive system.

Active position sense of knee joint of 20 dancers/20 sedentary were assessed at 20°-40°-60° of extension with/without visual feedback (w/woVF) to observe the mean error of matching angles (EoMA). Hamstring muscle flexibility was assessed with sit and reach test. We found that the flexibility of the right hamstrings was negatively related with active position sense of dancers at the target angles of 20° and 40° wVF (p < 0.05; p < 0.01). Additionally, the active position sense of the right knee joint (EoMA: 1.95 ± 2.91 degrees) was significantly better than the sedentary (EoMA: 4.2 ± 3.02 degrees) (p < 0.05) only at 20°wVF. Furthermore, the flexibility of left hamstrings was also negatively related with the active position sense of dancers only at the target angles of 20° wVF and woVF.
