What is this system?
Arrector pili muscle: little muscles in the hair follicle that make hair to stand.
Capillaries: Smallest body blood vessels and connect arterioles and venules
Hair: simple structure without important functions that is made of protein called keratin
Sebaceous gland: microscopic glands that create sebum that lubricates the skin and make it waterproof.
Touch receptor: the receptors that give signals to the brains that some part of the body is touching something
Sensory nerve: the nerve that passes impulses of receptors to the brain.
Pressure receptor: the receptor that catches the impulses of nerve that identifies when something is getting pressure and respond to the changes of the wall tension
Apocrine sweat gland: secrete hormones to the bloodstream , in case of then women are the ones in charge of the milk producing
Hair Follicle: the structure where the hair came from of the skin
Subcutaneous artery and vein: carry blood towards the heart they are critical in the circulatory system
Motor nerve: A motor nerve which carries impulses from the central nervous system ,that means that any time someone needs to move, the nerve is involved.
Merocrine sweat gland: are glands that extend to the skin to They help to regulate the body’s overall temperature
Epidermis: First layer of the integumentary system, it is made up of stratified squamous epithelium. This layer contains Keratin and Keratinocytes (Family of fibrous structural proteins, Keratinocytes are the principal cells of the epidermis), Melanocytes (Produce melanin), Melanin (provide protection against sun’s UV radiation and activates vitamin D. It also has dead cells that are replaced with living cells to form our skin.
Dermis: Intermediate layer that contains Collagen (support epidermis), Elastin (stretch the skin when move muscles or gain weight), Blood Vessels (nourish cells of skin), and Sensory Receptors (receive energy or stimuli from environment).
Hypodermis: Bottom layer of the integumentary system. It is a adipose and connective tissue.
