127 SkinThis Pacinian corpuscle was found within the hypodermis (a layer beneath the dermis). Pacinian corpuscles are sensitive to pressure and vibration. The corpuscle resembles an onion cut in x-section. The lamellar appearance is due to concentric layers of flattened endoneuronal cells. Identify the bloo...Pacinian corpuscle; SkinUCLA Histology
128 AdrenalThis is your best slide of the human adrenal cortex. The capsule is prominent as are the zones of the cortex, the zona glomerulosa, zona fasciculata, and zona reticularis. Deep to the zona reticularis should be the medulla but on this slide, instead of medulla there is a central zone of cortical cel...AdrenalUCLA Histology
129 Excision procedureThe following slides are a brief review of the excision procedure. The scalpel is angled outward away from the wound edge to ensure that the wound edges are beveled at about 45 o.Surgical MethodsKnowledge Weavers Dermatology
130 OvaryThis image at a relatively low magnification shows a large atretic tertiary follicle including the antrum, glassy membrance, theca interna and degenerating granulosa cells. The region of the degenerating granulosa is shown at higher magnification in image 205-10-2. UCLA Histology Collection.OvaryUCLA Histology
131 Decubitus ulcerA decubitus ulcer in an older woman in a nursing home. This was induced because the person was lying in one position for too long, and this compromised blood supply to the skin.Knowledge Weavers Dermatology
132 OviductThe epithelium of the oviduct consists of light and dark, ciliated and/or secretory cells surrounding the lumen. Note that the new individual lives in this environment for about 5 days. UCLA Histology Collection.OviductUCLA Histology

136 Brenner tumorBrenner tumors are comprised of solid to partly cystic epithelial nests surrounded by stroma composed of bundles of tightly packed spindle-shaped cells. The epithelial cells are polygonal and of squamoid type, with pale, eosinophilic cytoplasm and oval nuclei with distinct nucleoli and longitudinal ...Knowledge Weavers Human Reproduction
137 Gastrointestinal Tract - Junction of Dentin, Cementum, and Periodontal LigamentThis higher magnification view shows the junction of dentin with the surrounding acellular cementum and periodontal ligament (collagenous connective tissue). The cementum is elaborated by cells called cementocytes, visible here adjacent to the the cementum. Sections of blood vessels are also visible...UCLA Histology
138 SuturingThis demonstrates that a total of four throws should be made when tying the deep dermal suture, and if done properly, square knots are laid down. It is said that square knots provide optimum knot security.Knowledge Weavers Dermatology
139 SuturingThe short arm of the suture is then grasped with the needle holder, and then the non-dominant (left) hand crosses over the right hand as one tightens the knot pulling along the long axis of the wound.Knowledge Weavers Dermatology
140 Pineal GlandIdentify the corpora arenacea (brain sand) which are diagnostic of the pineal. Corpora arenacea are radio-opaque, which allows for identification of the pineal gland in X-rays and CT scans of the skull.

145 Excision procedureThis suture is tightened by crossing the non-dominant (left) and over the dominant (right) hand. This same sequence is continued until four loops have been thrown and then the suture is cut leaving ends approximately .5 cm long.Knowledge Weavers Dermatology
146 Circulatory System - Muscular ArteryA small muscular artery; note the extent of its tunica adventitia, almost indistinguishable from the surrounding connective tissue in which it is embedded. Identify collagen fibers and slender fibroblasts. UCLA Histology Collection.Circulatory System; muscular artery; tunica adventitiaUCLA Histology
147 PlacentaThis image illustrates numerous fetal villi surrounded by syncytiotrophoblast and the maternal blood space part of which is prominently filled with maternal red blood cells . There also appears to be a small region of fibrinoid. UCLA Histology Collection.PlacentaUCLA Histology
148 KidneyIn this trichrome stained section of the renal cortex there are sections of an interlobular artery and interlobular vein. Also identify the long medullary rays and several renal corpuscles. UCLA Histology Collection.Kidney; medullary rays; trichromeUCLA Histology
149 Skin tagsSkin tags. They are rather small, and have a pedunculated base giving them the appearance of a teardrop.Skin TagsKnowledge Weavers Dermatology
