1
Cells of these types of tissues have plasma membrane that can alter electrical potential from the normal resting potential
Excitable Tissue
2
Do all cells in body have RMP? If not, which ones don't?
No. dead cells
Stratum Corneum of epidermis
3
Altering the RMP is done by _____ in the plasma membrane to create _______
Proteins
Action/Graded Potential
4
Are all muscle cell types excitable?
Yes
5
Muscle attached to skeleton (mostly) longest muscle cell type, and are under voluntary control.
Skeletal
6
What is the appearance of the histology of skeletal muscle?
Skeletal - over lapping proteins
7
Muscle that is excitable, can conduct graded and action potentials, found in digestive tract, blood vessels, reproductive and respiratory systems
Smooth Muscle
8
How is the histology of smooth muscle different?
Not striated. Cells are smaller and spindle shaped.
9
Muscle found only in the heart. Striated, but with branching fibers. Intercalated disks appear between fibers that are actually gap junctions
Cardiac Muscle
10
Characteristic of Muscle that means it can conduct action potential in repsonse to a stimulus
Excitability
11
Characteristic of muscle tissue meaning it can shorten and lengthen to generate a force, they push different things
Contractability
12
Function of Smooth muscle
Function of Carciac Muscle
Function of skeletal muscle
Push Fluids or gases
Push Blood
Move skeleton
13
Characteristic of muscle tissue meaning it can be stretched beyond resisting length when it is relaxed, may or may not be functional
Extensibility
14
Characteristic of muscle tissue meaning that it after stretching it will resume its original length
Elasticity
15
Function of muscle done to skeletal structure, blood, or a substance encircled by the organ (i.e. food)
Produce Movement
16
The function that is only applicable to skeletal muscle
Maintain Posture
17
As skeletal muscle maintains posture, it also does this
Stabilizes joints
18
Function of muscle tissue , not all potential energy from ATP is converted to kinetic energy for work, some released as a different type of energy
Generate Heat
19
Why is the release of energy as heat a good thing (as long as it's not too much)?
Keeps the enzymes of body functioning.
20
Is all skeletal muscle attached to bone?
No, there are a few exceptions (palmaris longus)
21
Elongated cell known as a fiber (long and thin). Surrounded by plasma membrane and contains cytoplasm and organelles
Muscle Cell
22
The name for the plasma membrane of the muscle cell
Sarcolemma
23
Where is the endomysium in relation to the muscle cell?
Just outside the sarcolemma (superficial)
24
The name for the cytoplasm of muscle cells
Sarcoplasm
25
These type of organelles in the muscle cell are unique because there are multiple of them and they are peripherial
Nuclei
26
These type of organelles in muscle cells are unique because there are numerous amounts of them (not the nuclei), makes sense because muscle cells are involved in energy production and skeletal muscle uses a lot of energy
Mitochondria
27
Protein of muscle cells that stores extra oxygen, which is necessary for production of ATP
Myoglobin
28
Inclusions (aka storage granules) that store additional glycogen (fuel)
Glycosomes
29
The modified endoplasmic reticulum in the muscle cell, it is surround the myofibrils
Sarcoplasmic Reticulum
