A major coordinating center for sensory and motor signaling in the human brain is shown in the given sagittal section by the letter:
     
1. A
2. B
3. C
4. D

The reflex arc ends at:
1. sensory neuron
2. motor neuron
3. effector
4. receptor

The brain stem does not include:
1. medulla
2. pons
3. midbrain
4. cerebral cortex

Mark the correct statement:

The resting axonal membrane of a neuron:

1. is not polarized

2. has an excess of anions on the outside

3. is more permeable to potassium ions than to sodium ions

4. cannot be excited by a stimulus

Consider the characteristics of a certain part of the human brain:
I. It contains neurosecretory cells.
II. It is an important part of the limbic system.
III. It is a part of the diencephalons.

This part of the human brain is:

1. Hypothalamus

2. Medulla oblongata

3. Cerebellum

4. Amygdala

Consider the following statements.

(a) Occurs involuntarily and without conscious effort.
(b) At least no afferent and two efferent neuron required.
(c) Only motor neuron is involved in the action.
