51 Excision: suturingThe double loop is tightened by pulling the hands into their natural position, but the knot cannot be adequately tightened by pulling in that direction; the knot must be tightened by pulling the suture ends along the length (long axis) of the wound. (This is shown in the following slide)Knowledge Weavers Dermatology
52 PituitaryBecause of its physiological importance, several images of the pars distalis are included. In this one, recognize bluish basophils, abundant reddish acidophils, a probable chromophobe (with no cytoplasmic granules), and red blood cells.

56 Skeletal MuscleNote the alternating cross sectional and longitudinal fascicles of skeletal muscle that are characteristic of the tongue. Also note the difference in appearance of the connective tissue space. Identify the pockets of adipose tissue within this section, as well as the prominent nerve bundles, and blo...Skeletal Muscle; TongueUCLA Histology
57 PlacentaThis image is very useful for differentiating the fetal and maternal components of the placenta . One can readily identify the maternal blood space , fetal villi including one obvious tertiary villus . Fibrinoid is present in the area of fetal villi as well as in a region dominated by maternal decid...PlacentaUCLA Histology
58 Connective TissueThis low power view of the monkey heel shows epidermis, dermal connective tissue, a sweat gland, and the insertion of the Achilles tendon into the dark-pink heel bone. Fatty tissue can be seen in the bone marrow cavity. UCLA Histology Collection.Connective Tissue; epidermis; tendonUCLA Histology
59 Peripheral Nervous SystemVery low power view of two myelinated nerves. Good for epineurium and perineurium. Osmium stained so myelin is stained. UCLA Histology Collection.Peripheral Nervous SystemUCLA Histology

65 Central Nervous SystemPyramidal cells of the cortex have several dendrites and one axon emanating for the cell body. The cell body has a nucleus with a nucleolus. The dendrites are branched and taper as they leave the cell body. One slender axon can be seen emerging from the cell body. Darkly stained nuclei of neuroglial...Brain; Central Nervous System; cortex; pyramidal cellUCLA Histology
66 Male Reproductive SystemThe seminal vesicles are long coiled tubes with a distinct lamina propria. Note the convoluted nature of the vesicles lumen. The mucosa is highly folded, and the muscular coat is composed of two layers of smooth muscle - an inner circular layer, and a outer longitudinal layer. UCLA Histology Collect...male reproductive system; Seminal vesicleUCLA Histology
67 EarThis image shows the bony labyrinth filled with perilymph, containing the membranous labyrinth filled with endolymph. Within the ampulla of each semicircular canal is the crista ampullaris, which is a specialization of the membranous labyrinth. UCLA Histology Collection.Crista Ampullaris; EarUCLA Histology
68 Cells / Organelles - Developing BoneAnother area of the newborn rat knee, demonstrating a portion of developing bone, stained pinkish. The cells producing the bone are called osteoblasts. Identify a nucleus, nucleolus. The Golgi apparatus can be identified as the clear, central area. UCLA Histology Collection.UCLA Histology
69 Ingrown nail90% phenol is one of the agents advocated for destroying the nail matrix that grows at the base of the cul-de-sac beneath the proximal nail fold.Knowledge Weavers Dermatology
70 UterusIn the ischaemic phase of the menstrual cycle the secretory endometrial glands begin to degenerate and there is intraendometrial hemorrhage. UCLA Histology Collection.ischaemic endometriumUCLA Histology

74 Eye - Ciliary EpitheliumSome features of the double-layered ciliary epithelium can be observed in the plars plana region. The innermost layer (closest to the posterior chamber) is non-pigmented and the outermost layer is pigmented. The ciliary epithelium forms aqueous humor and secretes it into the posterior chamber. Aqueo...canal of Schlemm; ciliary epitheliumUCLA Histology
75 Eye - Ciliary BodyThe ciliary body is a ring-shaped structure that extends around the eyeball, posterior to the corneal - scleral junction (limbus). It consists of a double-layered epithelium, smooth muscle and stroma. Canal of schlemm is a landmark for the limbal region. The epithelium covers a flat portion of the c...canal of schlemmUCLA Histology
