epithelial tissue
covers or lines external or internal body surfaces
squamous simple epithelium
flat shaped, one layer thick
cuboidal simple epithelium
cube shaped, one layer thick
columnar simple epithelium
column shaped, one layer thick
columnar pseudostratified epithelium
column shaped, one layer thick but cells have different heights
squamous stratified epithelium
flat shaped, many layers thick
columnar stratified epithelium
column shaped, many layers thick
cuboidal stratified epithelium
cube shaped, many layers thick
transitional epithelium
found in bladder, ability to change/flex with how full the bladder is
connective tissue
connects, supports, binds or separates other tissues or organs, consists of cells embedded in a matrix
loose connective tissue
holds organs in place and connects skin to underlying muscle
loose connective tissue matrix
protein fibers
collagen fibers
protein fibers that provide strength
elastin fibers
proteins fibers that prove stretchiness
fibrous connective tissue
found mainly in tendons and ligaments
matrix of fibrous connective tissue
parallel collagen fibers
tendons
connect bone to muscle
ligaments
connect bone to bone at joints
adipose tissue
stores fat
cartilage tissue
consists of cells embedded in a flexible carbohydrate matrix
bone
matrix is made up of collagen fibers and has rigid, calcified ground substance (minerals) -compact and spongey
blood
matrix- liquid plasma, the fibers are soluble proteins that form during clotting (platelets)
muscle tissue
allows for movement, but it also helps stabilize our joints, maintain our posture and generate heat during activity, consists of voluntary and involuntary movements
nervous tissue
controls movements, sends and carries signals to and from the different parts of the body, and controls bodily functions
body cavities
fluid filled spaces in the body
diaphragm
muscle that separates cavities in chest and abdomen
hernias
occurs when an organ or tissue bulges through a weakness in a body wall
integumentary system
includes skin, hair, and nails
nervous system
controls most body systems; involved with learning and memory
skeletal system
provides support and protection for body
muscular system
generates body movement
respiratory system
involved in gas exchange
circulatory system
transports materials throughout the body
digestive system
breaks down food and absorbs nutrients
urinary system
removes wastes from body; includes kidney
endocrine system
releases hormones to regulate other body systems
reproductive system
involved in production of sperm and egg cells
sensory system
carries information about environment to the brain
distal
away from the point of attachment
superior
toward the head
superficial
towards the outer surface of the body
posterior
back side of the body
lateral
away from the midline of the body
proximal
towards the point of attachment
anterior
front side of the body
deep
away from the outer surface of the body
medial
towards the midline
inferior
away from the head
frontal section
divides the body int front and back halves
sagittal section
divides the body along a plane parallel to the midline
transverse section
divides the body horizontally, perpendicular to the midline
epidermis
the outermost layer of skin
keratin
limits water loss
melanin
pigment that gives skin color
dermis
the middle layer of skin
sweat glands in the dermis
produces sweat
blood vessels
help regulate body temperature
hair follicle
hair that grows from the dermis of the skin
arrector pili
cause hair to stand up, causes goosebumps
sebaceous glands
produce moisturizing oil for your skin called sebum
acne
clogged sebaceous glands
lips
do NOT have sebaceous glands
hypodermis
deepest layer of skin
1st degree burn
epidermis is damaged, ex. sun burn
2nd degree burn
epidermis and dermis are damaged
3rd degree burn
epidermis, dermis and hypodermic are damaged
