Q

What step (number) in reflex arcs where nerve impulse move along the axon of a sensory neuron toward the cell body located outside the cord

A

1

23
Q

What step (number) in reflex arcs where from the cell body of the sensory neuron, the impulses are picked up by an interneuron lies within the cord

A

2

24
Q

What step (number) in reflex arcs where The impulses are passed to the dendrites and the cell body of a motor neuron that lies ventrally within the cord.

A

3

25
Q

What step (number) in reflex arcs where The impulses will leave the cord by way of the ventral root traveling along the axon of the motor neuron going to the muscle fibers, which contracts

26
Q

REFLEXES CAN BE CATEGORIZED INTO ONE OF TWO LARGE GROUPS, WHAT ARE THESE?

A

Autonomic Reflexes (visceral) and Somatic Reflexes

27
Q

a group of reflex that are mediated through the autonomic nervous system and are not subject to conscious control

A

Autonomic Reflexes (visceral)

28
Q

(group of reflexes) These reflexes activate through smooth muscles, cardiac muscle, and the glands of the body

A

Autonomic Reflexes (visceral),

29
Q

(group of reflexes) They regulate body functions such as digestion, elimination, blood pressure, salivation and sweating

A

Autonomic Reflexes (visceral),

30
Q

Example of Autonomic Reflexes (visceral)

A

pupillary reflexes, ciliospinal reflex, salivary reflex

31
Q

(group of reflexes) Include all those reflexes that involve the stimulation of skeletal muscles by the somatic division of the nervous system

A

Somatic Reflexes

32
Q

(group of reflexes) An example of such reflex is the rapid withdrawal of a hand from a hot object

A

Somatic Reflexes

33
Q

(group of reflexes) An example of such reflex is the rapid withdrawal of a hand from a hot object

A

Somatic Reflexes

34
Q

stretch reflexes, crossed extensor reflex, superficial cord reflexes (abdominal cremaster and plantar reflexes) cranial nerve reflex test (corneal reflex, gag reflex) are example of?

A

Somatic Reflexes

35
Q

Includes contraction of abdominal muscles in the quadrant of the abdomen that is stimulated by scraping the skin tangential to or toward the umbilicus. This contraction can often be seen as a brisk motion of the umbilicus toward the quadrant that is stimulated.

A

Abdominal reflex

36
Q

A reflex action of the eye in response to focusing on a near object, then looking at distant object (and vice versa), comprising coordinated changes in vergence, lens shape and pupil size.

A

Accommodation reflex

37
Q

Jerking of the ankle when the Achilles tendon is hit with a tendon hammer while the foot is relaxed, stimulating the S1 reflex arc.

A

Achilles (L5 to S2) or Ankle Jerk reflex

38
Q

In infants up to one year of age, and also in older individuals with neurological damage, a spreading of the toes and extension of the big toe in response to stroking the side of the foot.

A

Babinski reflex

39
Q

A jerking of the forearm when the biceps brachii tendon is struck with a tendon hammer, stimulating the C5 and C6 reflex arcs.

A

Biceps reflex

40
Q

It is mediated through the trigeminal nerve.

A

Corneal reflex

41
Q

An involuntary blinking of the eyelids elicited by stimulation of the cornea

A

Corneal reflex

42
Q

Elevation of the scrotum and testis elicited by stroking of the superior and medial part of the thigh

A

Cremasteric reflex

43
Q

A kick caused by striking the patellar tendon with a reflex hammer just below the patella, stimulating the L2-L4 reflex arcs

A

Knee jerk or Patellar reflex

44
Q

A reduction of pupil size in response to an object coming close to the eyes

A

Pupillary Accommodation reflex

45
Q

A reduction of pupil size in response to light

A

Pupillary Light reflex

46
Q

Jerking of the forearm when the triceps tendon is hit with a reflex hammer stimulating the C7 and C6 reflex arcs

A

Tricep reflex

47
Q

Tests the somatic responses of cranial nerves IX and X

A

Gag reflex

48
Q

When the oral mucosa on the side of the uvula is stroked, each side of the mucosa should rise and the amount of elevation should be equal

A

Gag reflex

49
Q

Swallowing reflex induced by stimulation of the palate

A

Palatal reflex

50
Q

Swallowing reflex induced by stimulation of the palate

A

Palatal reflex

51
Q

Closing of the eyes in response to irritation of the conjunctiva

A

Conjunctival reflex

52
Q

Closing of the eyes in response to irritation of the conjunctiva

A

Conjunctival reflex

53
Q

Dilation of the pupil on the ipsilateral side of the stimulus

A

Ciliospinal reflex
