PHTY2030 Anatomy Exam
Questions And Answers
cerebral hemispheres - ANSWER The right and left halves of the cerebrum.
cerebral cortex (cerebrum) - ANSWER The thin layer of interconnected neural cells that
forms a surface layer on the cerebral hemispheres (like bark on a tree). It is the body's
ultimate control and information processing center. It is what makes humans
upper-level thinking beings as opposed to animals
frontal lobe - ANSWER Primary Motor Cortex:
- Voluntary movement! (contralateral)
Motor Association Cortex:
- Motor Planning and execution! (contralateral)
Frontal Eye Fields:
- Voluntary eye movement (contralateral)
Prefrontal Cortex:
- Personality
- Decision making
- Memory
- Learning
Broca's Area: Speech Center
- Planning of speech
parietal lobe - ANSWER Primary somatosensory cortex: Awareness of somatosensation
- Sharp/Blunt
- Hot/Cold
- Rough/Smooth
- Proprioception
Somatosensory association cortex: Analysis and memory of somatic sensation.
Posterior association area: Receives information from visual, auditory, and
, somatosensory association cortex's
temporal lobe - ANSWER Primary Auditory Cortex: Awareness of sound
Auditory Association Cortex: Analysis and memory of sound
Primary Olfactory Cortex: Awareness of smell
Olfactory Association Cortex: Analysis and memory of smell
Wernicke's Area: Comprehension and understanding of written and spoken language
occipital lobe - ANSWER Primary Visual Cortex: Awareness of visual stimulus
Visual Association Cortex: Analysis and memory of visual stimulus (facial recognition,
visual association with other senses).
Cerebellum - ANSWER Movement coordination
Balance (Vestibuloceribellar system)
Speech
Eye movement
basal ganglia - ANSWER - Motor control
- Motor learning
- Some emotions
Brainstem - ANSWER Midbrain, pons, medulla oblongata.
Autonomic survival functions, pathway for many cranial nerves.
olfactory nerve (CN1) - ANSWER sense of smell
optic nerve (CN2), sensory - ANSWER It is a sensory nerve (Afferent), it transmits sight
from the retina to the brain, it enters through the optic canal, passes through thalamus
- Transmits sight to brain
Occulomotor Nerve (CN3), motor - ANSWER eye movement up down sides (motor)
passes through midbrain
Trochlear Nerve (CN4) - ANSWER eye movement down (motor) passes through midbrain
trigeminal nerve (CN5) (SENSORYMOTOR) <--> - ANSWER sensory: face, teeth, tongue
motor: muscles of mastication
Passes through pons
