Superficial Reflex

The ___ (abdominal, cremasteric, and plantar reflexes) are initiated by stimulation of receptors in the skin and mucosae.

motor neuron

The ___ conducts efferent impulses from the integration center to an effector organ.

Receptor

The ___ is the site of stimulus action.

integration center

The ___ may be as simple as a single synapse between a sensory neuron and a motor neuron, where information is processed.

sensory neuron

The ___ transmits afferent impulses to the CNS.

effector

The ___, a muscle fiber or a gland cell, responds to efferent impulses by contracting or secreting, respectively.

oculomotor

Which cranial nerve is the motor nerve for both the pupillary light reflex and the consensual reflex?

vagus

Which cranial nerve is the motor nerve for the Gag reflex?

optic

Which cranial nerve is the sensory nerve for both the pupillary light reflex and the consensual reflex?

Trigeminal

Which cranial nerve is the sensory nerve for the Corneal Reflex?

glossopharyngeal

Which cranial nerve is the sensory nerve for the Gag reflex?

facial and oculomotor

Which cranial nerves are the motor nerves for the Corneal Reflex?

Radial

Which nerve innervates the Triceps Brachii and Posterior Forearm Extensor Muscles?

musculocutaneous

Which nerve innervates the Triceps Brachii and Posterior Forearm Extensor Muscles?

obturator

Which nerve innervates the adductor group?

ulnar

Which nerve innervates the anterior forearm flexor muscles, intrinsic mucsles of the hand?

median

Which nerve innervates the anterior forearm flexor muscles, lateral palm, and finger?

common fibular

Which nerve innervates the biceps femoris, tibialis anterior, and the extensor muscles of the toes?

axillary nerve

Which nerve innervates the deltoid muscle and teres minor muscle?

phrenic

Which nerve innervates the diaphragm?

femoral

Which nerve innervates the quadriceps femoris group and the sartorius muscle?

salivary reflex

Which reflex reacts to many forms of stimulus and uses the glands as the effectors?

Stretch Reflex

___ are important for maintaining and adjusting muscle tone for posture, balance, and locomotion by tapping a tendon or ligament, which stretches the muscle to stimulates the muscle spindles and causes reflex contraction of the muscle or muscles.

Crossed-Extensor Reflex

___ consists of a flexor, or withdrawal, reflex followed by extension of the opposite limb.

pupillary light reflex

___ involves a pupillary reaction in response to light being shone directly into the eye.

consensual reflex

___ involves a pupillary reflex in response to light being shone into the opposite eye.

ciliospinal reflex

___ involves a pupillary reflex in response to pain stimulus on the neck and torso.
