Motor aphasia may result due to the lesion of:

The emotion of fear is processed by:

An injury to the cerebellum would most probably lead to:

The seat of the origin of the vagus nerve is:

When a person enters a dark room, in the rods of his eyes:

1. cGMP levels are high.

As a sound grows in intensity while remaining at one frequency the basilar membrane:

Identify the correct statement regarding the semicircular canals of the human internal ear:
1. There are three of them, all oriented in the same direction but sensitive to all possible head motions.
2. There are six of them, organized in three pairs with each pair sensitive to one kind of motion, such as up or down.
3. There are three stacked in a random fashion; all contributing to fluid flow through the utricle and saccule which interpret the direction of head movement from the resulting
fluid flow.
4. There are three oriented in different planes so that angular acceleration can be detected.

The skeletal muscles in humans are innervated by:

1. somatic neural system
