Visual reflexes in the brain are coordinated by:
1. cerebellum
2. superior colliculus
3. inferior colliculus
4. parietal cortex

The longest cranial nerve with a large number of parasympathetic fibers is:
1. phrenic
2. spinal accessory
3. vagus
4. thoracic

The receptors for deep pressure and vibrations are:
1. proprioceptors
2. nociceptors
3. Meissner's corpusles
4. Pacinian corpuscles

A proprioceptive sensory receptor organ that senses changes in muscle tension is the
1. Golgi tendon organ
2. muscle spindle
3. Pacinian corpuscle
4. Merkel’s disc

Odors can alter our moods:

1. Because sensory input from olfaction is routed through the limbic system.

2. Because odors act as neurotransmitters and alter brain chemistry.

3. Because odors are satisfying to our sense of hunger.

4. Odors do not alter mood.

The sensory organ of hearing and the receptors are located in:
1. scala vestibuli
2. semicircular canal
3. scala tympani
4. cochlear duct

Static equilibrium is regulated by:

1. semicircular canals
2. vestibule
3. cochlea
4. None 

Photoreceptors rods or cones are unique as they are activated by:
1. depolarization
2. hyperpolarization
3. repolarization
4. decomposition

The extraocular muscles are innervated by all the following cranial nerves except:
1. oculomotor
2. trochlear
3. abducens
4. optic

The outermost meninx that provides a thicker and protective layer is the:
1. dura mater
2. arachnoid mater
3. pia mater
4. gray mater
