where can epithelial tissue be found in the human body
Epithelium Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body.
Human skin Epidermis is divided into several layers where cells are formed through mitosis at the innermost layers. They move up the strata changing shape and composition as they differentiate and become filled with keratin. They eventually reach the top layer called stratum corneum and are sloughed off, or desquamated. This process is called keratinization and takes place within weeks. The outermost layer of the epidermis consists of 25 to 30 layers of dead cells.
Tactile corpuscle They are distributed on various areas of the skin, but concentrated in areas especially sensitive to light touch, such as the fingers and lips.[3][4][5][6][7] More specifically, they are primarily located in glabrous skin just beneath the epidermis within the dermal papillae.[8]
Adipose tissue Most of the remaining nonvisceral fat is found just below the skin in a region called the hypodermis.[26] This subcutaneous fat is not related to many of the classic obesity-related pathologies, such as heart disease, cancer, and stroke, and some evidence even suggests it might be protective.[27] The typically female (or gynecoid) pattern of body fat distribution around the hips, thighs, and buttocks is subcutaneous fat, and therefore poses less of a health risk compared to visceral fat.[28]
