A&p Nerve Lab Questions

Front 1

Corneal Reflex

Back 1

type of somatic reflex that is mediated through trigeminal nerve

Front 2

Reflex arcs

Back 2

5 components

1.) receptor= site of stimulus
2.) sensory neuron transmits afferent impulses to CNS
3.) integration center= 1 or more neurons in CNS

4.) motor neuron conducts efferent impulses from the integration center to an effector organ

5.) effector muscle fibers/glands respond to impulses by contracting/ secreting

Front 3

Somatic Reflexes

Back 3

- reflexes involve stimulation of skeletal muscles by somatic division of NS

ex.) rapid movement of hand from hot object

Front 4

Spinal Reflexes

Back 4

-initiated & completed at spinal cord
-occur w.o involvement of higher brain centers
-found in animals w/ destroyed brains and functioning spinal cords

Front 5

Stretch Reflex

Back 5

-maintain posture, balance, locomotion

-initiated by tapping tendon, which stimulates muscle tendon is attached to

-causes reflex contraction
** reciprocal inhibition.. cause to relax and prevent from resisting contraction

Front 6

Structure of a nerve

Back 6

-Endoneurium
-Perineurium
-Fascicle
-Epineurium
