Study guide for Module #9

1.
A)Somatic receptors: Sensory receptors in the skin, muscle and tendons.
b) Visceral receptors: Sensory receptors in the internal organs
c) Special receptors: Sensory receptors in specific locations
d) Mechanoreceptors: Sensory receptors which respond to movement
e) Thermoreceptors: Sensory receptors which respond to heat or cold
f) Photoreceptors: Sensory receptors which respond to light
g) Chemoreceptors: Sensory receptors which respond to chemicals
h) Nociceptors: Sensory receptors which respond to pain or excess stimulation.
i) Cutaneous receptors: Receptors in the skin
j) Proprioceptors: Receptors in the muscles and tendons.
k) Sensory receptors: An organ which responds to a specific type of stimulus by ultimately triggering an action potential on a sensory neuron.

2.
Somatic

3.
a) In the sympathetic division:

The the preganglionic neuron is short while the postganglionic neuron is long.

In the parasympathetic division:

The preganglionic neuron is long while the postganglioni neuron is short.

b) Placement:

The sympathetic division is placed in the thoracic and lumbar region of the body while the parasympathetic division is found in the brainstem and sacral region of the spinal cord.

c) Position of ganglia:

I am not sure about this one.

e) Somatic--responds to heat or cold
f) Special--responds to light
g) Special--responds to movement
h) Somatic--responds to movement

The cerebral cortex's projection tells me where the pain is, in the neck.
The modality tells me what kind of a stimulus it is, pain.

6.
a) free nerve endings--cutaneous receptors (responds to heat,cold,pain and movement)
b) Merkel's disk--Cutaneous receptors (responds to movement)
c) hair follicle receptors--cutaneous receptors (responds to movement)
d) Pacinian corpuscules--cutaneous receptors (responds to movement and pain)
