Study Notes
Integumentary System and Cutaneous Sense Receptors
- The epidermis consists of the stratum corneum, a thick layer continually shedding and replaced by cells below, and is waterproof due to glycolipids between cells.
- The dermis is derived from mesoderm and includes the papillary layer, which is thin and vascular, and the reticular layer, which is deep and contains blood vessels, nerves, and glands.
- The hypodermis is a layer of adipose and areolar connective tissue underlying the skin, binding it to underlying structures.
- Skin coloration is influenced by melanin, carotene, and hemoglobin, with melanin being responsible for most variations in skin color among people.
- Epidermal derivatives such as hair, hair follicles, and nails consist of specialized keratinized cells and are associated with structures like the hair bulb, hair matrix, and hair papilla.
- Exocrine glands in the skin include sebaceous glands that secrete sebum, sudoriferous glands that regulate body temperature and remove body wastes, ceruminous glands that secrete ear wax, and mammary glands that produce milk.
- Cutaneous sense receptors are specialized components of the nervous system that respond to external stimuli, including mechanoreceptors sensitive to touch, pressure, and vibrations, thermoreceptors sensitive to temperature changes, and nociceptors sensitive to pain.
- The skeletal system is divided into axial and appendicular portions, with the axial skeleton consisting of the skull, hyoid, vertebral column, and thorax, totaling 80 bones.
- The skull includes cranial bones that surround the brain, facial bones, and auditory ossicles used for sound transmission.
- The hyoid bone, which does not articulate with any other bone, assists in swallowing and serves as an attachment site for muscles of the tongue, neck, and pharynx.
