BIOD 152 Module 2: Neuroanatomy and Functions of
The Brain Questions and Answers
BIOD 152 Module 2 Exam
Anatomy and Physiology 2 (Portage Learning)
, ● Dura Matter (menix): This is the most superficial layer of the brain meninges
● Pia mater: layer of meninges tightly attached to the brain.
● The transverse fissure separates the cerebrum from the cerebellum
● Median longitudinal fissure separates the right and left cerebral hemispheres.
● Cerebrum: largest portion of the brain
● Cerebellum: The anterior lobe receives information from the body trunk.
● Frontal lobe: decision making
● Association area: acts to coordinate multiple sources of sensory information.
● Damage:
○ Wernicke's area: difficulty understanding language but is still able to
speak fluently. The patient's dermatomes are intact
○ radial nerve: is not able to extend his left wrist or fingers.
○ Saphenous nerve: decreased sensation over the posterior surface of the
thigh.
○ Sciatic nerve: decreased sensation over the posterior surface of the
thigh.
○ Broca's area: difficulty understanding speech sounds
○ Ulnar nerve- A patient is unable to extend his fourth and fifth digits when
asked to open his hand.
○ Femoral nerve: hip flexion, knee extension
○ Phrenic nerve: ventilator post car accident
● Symptom of ALS: Impaired ability to swallow
● Alzheimer's disease impacts which region(s) of the brain? Occipital lobe, Frontal
lobe,Parietal lobe,Hippocampus
● Carpal tunnel syndrome: A patient has decreased hand strength in her right hand.
She also has numbness in her first three digits. What is most likely the cause?
● Trigeminal nerve: The maxillary branch receives information from the upper lip.
● lumbar plexus: is from spinal nerves: T12-L04, L01-L04 there are two divisions:
anterior and posterior
● Sacral plexus is formed from L04- S04
● Brachial plexus: There are anterior and posterior divisions
● sympathetic trunk ganglia: contain the ganglia from the sympathetic nervous
system that controls the effector organs in the trunk, head and limbs
● C3- C5: A patient is on a ventilator post a car accident. What region of the spine
is most likely damaged?
● Ciliary ganglion: contain the ganglia for the parasympathetic nervous system
that target the intrinsic eye muscles to change the diameter of the pupil.
● 4th ventricle: located anterior to cerebellum
All the following are functions of the hypothalamus except:
