Abstract:
Skin biopsy specimens of normal llama skin were examined histologically. Adnexal structures similar to those of most other domestic mammals included epitrichial sweat glands, sebaceous glands and arrector pili muscles. Unique features of normal llama skin included a very thick dermis with marked differences between superficial and deep dermis, prominent cutaneous vascular plexuses, unidentified cells with eosinophilic granules within the adventitia of the vascular plexuses, both simple and compound hair follicles, 'metatarsal glands', 'interdigital glands', footpad glands and the absence of eyelid tarsal glands.

01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

01:27Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
01:26Histology of the Large Intestine
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...
01:21Layers of the Epidermis
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...
