1. C. Muscle Tissues Skeletal muscle tissue (“voluntary”)
Long, threadlike cells
Striations: alternating light and dark cross-markings
Each cell has many nuclei just beneath the cell membrane.

2. Muscle Tissues (cont.) 2. Smooth muscle tissue (“involuntary”)
No striations
Cells are shorter than skeletal muscle, spindle-shaped, and have one, centrally located nucleus.
Line walls of internal organs

3. Muscle Tissues (cont.) 3. Cardiac muscle tissue – heart
Striated and joined end-to-end
Each cell has only one nucleus ???
How would you be able to differentiate b/t skeletal and cardiac muscle tissue, since both are striated?

4. D. Nervous Tissue Nervous tissue is See Table 5.5, p.107!!!
found in the brain, spinal cord, and nerves.
made up of:
Neurons: nerve cells
Neuroglial cells: helper cells
“glia” = glue
Support and bind components of nervous tissue to each other and to blood vessels
See Table 5.5, p.107!!!
