Quiz 5 - Cell Organization: Tissues and Organs (lectures) Flashcards
What anchors cells together? what connects them?
cytoskeleton
cytoskeleton
joins cells together
T/F: Most cells are connected to other cells
T
cells form together to make __ and__
tissues and organs
4 types of tissues
- epithelial
- connective
- muscle
- nervous
function of epitheleal cells
deal with one set of cells that aren’t you
function of connective tissues
- hold things together
T/F all connective tissues fall in the same category
F
function of muscle tissue
- allows the body to do work
- causes cytoskeleton and muscle contraction
function of the nervous tissue
- allows for rapid communication throughout the body
example of epithelial tissue
- skin
- lung tissue
- ## digestive tract
T/F stem cells can form into different types of cells
T
T/F stem cells are found in only one place
F: stem cells are found throughout the body
exampes of connective tissues
- tendons
- ligaments
- cartilage
- fat
- blood
- bone
T/F: bones are alive
T
T/F: there are both bone making and bone eating cells
T
What are voluntary movements of muscle tissue?
you decide the movements
what are involuntary movements within the body?
- automatic movements
- you don’t have to think about them for them to happen
cardiac muscle: voluntary or involuntary?
involuntary
example of a cardiac muscle
- heart muscle
example of involuntary muscle movement
- eating
- breathing
T/F: muscles work/fire on their own
F: they are initiated by an electrical signal which comes from your nerves through communication with your brain
main function of nerves:
- send electrical signals
nervous tissue
- allows for rapid voluntary and involuntary communication through electrical signals
