Answer 6

• Voluntary/Striated Muscle tissue forms voluntary muscles such as skeletal muscle, is striated/striped in appearance and is controlled by a person’s will. Exp biceps
• Involuntary/Smooth Muscle tissue is controlled by the autonomic nervous system. Also known as Visceral muscle tissue, as it lines the walls of hollow organs such as the stomach. A person does not control movement of involuntary muscles. Exp muscles that blink the eye.

Question 8

Nerve tissue Composed of neurons/nerve cells, acts as the functional unit of the nervous system. What are the two properties of nerve tissue?

Answer 8
