BIOS252 EXAM 2 ANATOMY &
PHYSIOLOGY II EXAM 2025 GUIDE
GRADED A+ | CHAMBERLAIN
Broca's area:
- correct answer –
-referred to as the area for production of speech
-involves coordinated contractions of your speech and
breathing muscles that enable you to speak
-works closely with the primary motor area as well as a
premotor area to make speech happen
-damage to this area can cause a person to not be able to form
words in order to articulate a thought.
Lumbar nerves function
- correct answer - -lower limb movement(hip, leg, foot)
Thoracic nerve function
- correct answer –
,-truck control
-temp regulation
-abdominal muscles
Coccygeal nerve function
- correct answer - sensory and motor innervation to their
respective dermatomes and myotomes
List and describe the layers of the meninges.
- correct answer - dura mater
arachnoid mater
pia mater
Dura mater:
- correct answer - -outer periosteal layer
-most superficial of the three spinal meninges
-thick strong layer composed of dense irregular connective
tissue
-surrounds spinal cord and is separated from vertebrae by
epidural space
Arachnoid mater:
, - correct answer - -middle of the meningeal membranes
-thin, avascular covering comprised of cells and thin, loosely
arranged collagen and elastic fibers
-adheres to dura and is separated from pia by fibers spanning
the subarachnoid space that is filled with cerebrospinal fluid
(csf)
Pia mater:
- correct answer - -innermost meninx
-thin transparent connective tissue layer that adheres to the
surface of the spinal cord and brain
-delicate membrane that follows contours of spinal cord
-continues inferiorly as a fibrous terminal filum that fuses with
dura to form coccygeal ligament
Satellite cells function
- correct answer - -surround somas of neurons in the ganglia
-provide electrical insulation and regulate chemical environment
of neurons
Microglial cells function
