1
Q
What are the 3 types of muscles?
A
Skeletal, smooth, cardiac
2
Q
What are the 5 properties that muscle tissue share?
A
excitability, conductivity, contractility, elasticity, extensibility
3
Q
What is exctibility?
A
Ability of a cell to respond to a stimulus (chemical, stretch)
4
Q
What happens when a muscle cell is stimulated?
A
A local electrical change occurs then sweeps across the entire plasma membrane
5
Q
What is conductivity?
A
Electrical change that travels along the plasma membrane during a muscle or nerve impulse
6
Q
What is contractility?
A
When contractile proteins with muscle cells slide past one another and the muscle cell shortens
7
Q
What is elasticity?
A
The ability of a muscle cell to return to its original length
8
Q
What is extensibility?
A
Lengthening of a muscle cell
