Bone Head
55
What is the function of Osseous Tissue
It is the Structural Unit of Compact Bone
56
How does the structural organization of CT differ from Epithelial Tissue?
Connective tissue is made of cells and matrix. Epithelial tissue is made of too many cells and has special characteristics
56
Explain how bone tissue is different from a bone?
Bone tissue is only a tissue. Bone is an organ made of bone tissue.
57

Voluntary Muscle Movement
59
Define Intercalated Disc?
The junction between 2 cardiac muscle cells
60
How is cardiac muscle tissue different from skeletal muscle tissue?
Cardiac Muscle tissue has branching and intercalated discs.
61
How is smooth muscle tissue different from skeletal muscle tissue different from skeletal muscle tissue and how is it different from cardiac muscle tissue?
Skeletal muscle doesn't branch or have intercalated discs. Smooth muscle is made of spindle shaped cells. Cardiac is multiple large cells.

What is the function of Nervous Tissue?
Carry electrical signals
66
Why are neuroglia found in nervous tissue
To protect and nourish
67
In what ways are white matter and gray matter different?
Gray matter is on the inside of white matter because gray matter contains neuron cell nucleus
68
What is myelin?
It is a sheath that covers an axon.
69
Why are some neuronal processes myelinated?
Protects the axon if myelinated it carries the electrical impulses better
70
What is the node of Ranvier
The edge of of the axon, showing the end and beginning of a new axon.
71
What is the function of the Node of Ranvier?
It is essential for action potential
72

Connected to the Spinal Cord and extend through the body
76
What is the function of Nerves?
Send electrical signals that help you feel sensations and move your muscles
77
