The integumentary system Flashcards
(43 cards)
superior/inferior
superior-toward the head end of the body
inferior-away from the head
anterior/posterior
anterior-means near or towards the front of something
posterior-further back in position; of or nearer the rear or hind end
superficial/deep
superficial-one structure is located more externally than another, or closer to the surface of the body
deep- located on the inside of the body/structure
lateral/medial
lateral-away from the midline of the body
medial-s a position toward the midline of the body
proximal/distal
proximal-toward or nearest the trunk or the point of origin of a part
distal-away from or farthest from the trunk or the point or origin of a part
Cell Membrane
Controls what goes in and out of cell
Nucleus
brain of the cell
Cytoplasm
hold other organelles in place
Mitochondria
makes energy
Golgi Apparatus
packages proteins
Endoplasmic Reticulum
transports proteins
Ribosomes
makes proteins
Lysosome
disposes of waste
Epithelial Tissue
Sheets of cells that cover the exterior surfaces of the body
Nervous tissue
Allows the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
Muscle tissue
Responds to stimulation and contracts to provide movement, and occurs as three major types:
Skeletal, Smooth, Cardiac
Connective tissue
Binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body
hair
hair has various functions such as protection against external factors, sebum, apocrine sweat and pheromones production and thermoregulation
(superior)
hair follicle
A hair follicle anchors each hair into the skin (superior )
hair root
The main function of root hairs is the uptake of water and nutrients from the rhizosphere (superior)
nails
The nail functions by protecting the digits and contributing to tactile sensation (superior extremity)
Lunula
The lunula has a primary structural role in defining the free edge of the distal nail plate (superior extremity)
cuticle
The cuticle is a diffusion barrier limiting water and solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack (superior extremity)
Nail root
It produces most of the volume of the nail and the nail bed.(superior extremity)
