Tissues Flashcards
(36 cards)
4 primary types of tissues
nervous, muscle, epithelial, connective
Homeostasis
balance of materials and energy that keep you alive
cell specialization
every cell in the body has a specific job description related to maintain homeostasis
cell body
the life support
dendrites
collect signals from other cells to send back to the soma
axon
carries messages to neurons muscles and glands
nervous tissue
control and communication
muscle tissue
movement
epithelial tissue
cover and protect the body
connective tissue
provide support
neurons
specialized building blocks of the nervous system
glial cells
provide support and instillation
what is well vascularized
muscle tissue
three different types of muscle tissue
skeletal, cardiac, and smooth
skeletal muscle tissue
attaches to all the bones in the skeleton and provides support
long straight cells and obvious striations with multiple nuclei
cardiac muscle tissue
only found in the heart, Regular contractons to propel blood through the circulatory system.
Has a branching structure
smooth muscle tissue
lines the walls of most of your blood vessels and hollow organs(digestive and urinary tracks)
no striations but its packed together and is uni nucleate
five types of epithelial tissues
squamous cubedal columnar ciliated glandular
proper epithelium
covers and lines the outer and inner body
gladular epithelium
forms the glands and secretes hormones and other substances
primary epithelium
protects the whole body inside and out
avascular
not supplied by blood vessels
are squamous cells bigger or smaller than columnar and are they cheaper or more expensive than columnar cells
they care smaller and cheaper than columnar
layer of simple epithelium
one layer
