Smooth muscles are managed by what? (Involuntary)
Autonomic nervous system - which is beyond our control. (EX.GI tract)
This structure is known as the "little brain" ;
and
Helps control muscle contractions to produce coordinated movements for maintaining balance(equilibrium), moving smoothly, and sustaining normal postures
Cerebellum

Blood
What are the three types of muscle tissue?
Glia (neuroglia) – Found where?
and what do they do?
CNS
Provide support and protection for neurons
True or False: Gustatory receptors are extremely sensitive but easily adapt (become fatigued)
FALSE: Olfactory receptors are extremely sensitive but easily adapt (become fatigued)
These muscles oppose, or reverse, a particular movement
Antagonists muscles
Brachi/o
Arm (Brachial)

This structure controls hormone secretion by anterior and posterior pituitary glands; therefore, it indirectly helps control hormone secretion by most other endocrine glands.
Hypothalamus
The ear functions in hearing and in equilibrium and balance contain Receptors called:
Mechanoreceptors
What do Interneurons do?
Conduct impulses from sensory neurons to motor neurons; also known as central or connecting neurons
Encephal/o
