protect
cushion
insulate
energy source
transitional locattion
bladder
stratified Squamous location
epidermis
`areolar CT description and function
contains fibroblasts, and macrophages
has all 3 types of protein fibers
ground substance is made of hyaluronic acid
reduces friction
ptotection
elastic CT description and function
contains fibroblasts
has elastic protein fibers
stretch and recoil
hyaline cartilage description and function
has thin collagen protein fibers
covers surface of long bones
provides support
flexible
fibrocartilage description and function
has collagen fibers
absorb shock
elastic cartilage description and function

layers of the skin
epidermis
dermis
hypodermis
regions of the dermis
(1) papillary
(2) reticular
layers of the epidermis
(1) stratum corneum
(2) stratum basale
glands in the dermis
sebaceous (oil)
attached to the hair follicule
sudoriferous (sweat)
muscle in the dermis
arrector pili muscle
parts of the hair in the skin
hair bulb (root)
hair follicule (hair is found)
hair shaft (hair itself)
keratinocyte location and function
produce proteins
above melanocyte
melanocyte location and function
produce melanin
along the basal layer
what is the most widespread and abundant type of tissue?
connective tissue
what is the most common type of cartilage?
hyaline cartilage
cartilage is composed of
extracellular matrix
chondrocytes that live in lacunae
fibers: collagen and elastin
what is the function of ground substance in CT
supports the cells and fibers
helps determine the consistency of the matrix
what is found in the lacuna
chondrocyte
differences in protein fibers
collagen -thickest
elastic- net like
retiular- thin
