BIOL 2220 Final Exam Questions and
Answers 100% Pass

Describe the development of the brain - ✔✔1. the ectoderm thickens along the midline, forming the

NEURAL PLATE


2. the neural plates invaginates to form a neural groove with neural folds (the sides of the grooves =

folds)


3. the neural folds FUSE to form the neural tube


4. neural tube DETACHES from the ectoderm & descends into the middle of the embryo -- this forms the

CNS


5. neural crest develops as offshoots of neural folds (crests become neural ganglia)


Relate embryonic regions to the structures of the adult brain - ✔✔Brain Vesicles:


- Prosencephalon gives rise to telencephalon (cerebrum) and diencephalon (thalamus, hypothalamus,

epithalamus, retina)


- Mesencephalon gives rise to the midbrain


- Rhombencephalon gives rise to the myelencephalon (medulla oblongata) and metencephalon (part of

brainstem, pons, cerebellum)


Identify the ventricles of the brain - ✔✔- Brain ventricles = expansions of the lumen of the neural tube


- ventricles are continuous with one another & spinal cord


- filled with cerebrospinal fluid

- ependyma lines ventricles (helps make CSF)


Identify the ventricles of the brain - ✔✔Lateral Ventricles:


- within each hemisphere of the cerebrum


- 2 lateral ventricles are separated by SEPTUM PELLUCIDUM


- 2 lateral connected to third ventricle




Third Ventricle:


- connected to lateral & runs thru diencephalon




Fourth Ventricle:


- connected to 3rd & central canal of spinal cord


Interventricular Foramen - ✔✔- connects lateral ventricles to third


Cerebral Aquaduct - ✔✔connects the third and fourth ventricles


Openings - ✔✔- allow fluids outside brain to be connected to fluid on inside


- Lateral apertures: opening to fourth ventricle, one on each side


- Median aperture: top/root of fourth ventricle


Describe the surface anatomy of the cerebrum, its lobes and its functional regions. - ✔✔...


Surface anatomy of cerebrum - ✔✔gyri: elevated parts of the folds


sulci: depressions between gyri

longitudinal fissure: line that separates the left & right cerebral hemispheres


transverse fissure: separates the cerebrum from other parts


Cerebrum lobes - ✔✔- Frontal


- Parietal


- Occipital


- Temporal


- Insula—rest of the brain is folded around, internal, not visible from outside


Functional Regions of Cerebrum - ✔✔1. cerebral cortex


- outer/superficial part


- made up of gray matter (cell bodies of neurons & unmyelinated axons)


2. white matter


- deep to cortex


- Made up of myelinated neurons (lipids is what makes it white)


3. basal nuclei (Internal islands of gray matter inside white matter)


List the specific functional areas of the cerebral cortex, and identify their general purpose. - ✔✔The

cerebral cortex is the conscious mind—associated with self-awareness, communication, memory, &

voluntary movement


Cerebral Cortex Functional Areas - ✔✔motor, sensory, association


Motor (4) - ✔✔1. Primary Motor Cortex


- sends motor impulses to allow movement

2. Premotor Cortex


- LEARNED motor skills (goes to premotor before primary)


- sends signal to primary to actually do the movement


3. Broca's area


- in LEFT hemisphere only


- Associated with SPEECH (muscles in mouth, lungs, larynx, etc.)


- Same spot on right hemisphere controls BODY LANGUAGE


4. Frontal Eye Field


- allows us to voluntarily move our eyes (see a bird fly from left to right)


Sensory (7) - ✔✔1. Primary somatosensory cortex


- spatial discrimination (determines where signal is coming from on body)


2. Somatosensory association cortex


- integrates all of the sensory info that goes to primary


3. Visual Areas


- Primary visual cortex: brings info from retina


- Visual association area: uses experience to interpret (not just a bird, an eagle)


4. Auditory Areas


- Primary auditory cortex: receives info from inner ear


- Auditory association area: uses experience to interpret


5. Olfactory cortex (detects odor)
