Divisions of Brain Flashcards
1
Q
brainstem
A
- connects spinal cord to cerebrum
- contains medulla oblongata, pons, midbrain, and reticular formation
- location of cranial nerve nuclei
2
Q
medulla oblongata
A
- most inferior part of brain stem
- regulating heart rate, blood vessel diameter, respiration, swallowing, vomiting, hiccupping, coughing, and sneezing
3
Q
pons
A
- superior to medulla oblongata
- relay information between cerebrum and cerebellum
- site of reflex centers
4
Q
midbrain (mesencephalon)
A
- superior to pons
- visual reflex center
- auditory pathway
5
Q
reticular formation
A
- scattered throughout brain stem
- controls motor control, pain perception, rhythmic contractions and sleep wake cycle
6
Q
cerebellum
A
- attached to brainstem- posterior to pons
- controls muscle movement and tone
- intentional movement and learning motor skills
7
Q
diencephalon
A
connects brainstem to cerebrum
- relay and homeostatic functions
- contains thalamus, subthalamus, epithalamus, and hypothalamus
8
Q
thalamus
A
- largest part of diencephalon
- major sensory relay center
- influences mood and movement
9
Q
subthalamus
A
- inferior to thalamus
- involved in controlling motor functions
10
Q
epithalamus
A
- superior and posterior to thalamus
- contains habenula- sense of smell (emotional and viscereal response)
- pineal gland- sleep wake cycle
11
Q
hypothalamus
A
- most inferior portion
- maintaining homeostasis and regulates endocrine function
- pituitary gland- secretion of hormones
12
Q
cerebrum
A
controls conscious perception, thought, and conscious motor activity
-contains basal nuclei and limbic system
13
Q
basal nuclei
A
- located in inferior cerebrum, diencephalon, and midbrain
- controls muscle activity
14
Q
limbic system
A
- parts of cerebrum and diencephalon
- survival functions- memory, reproduction, and nutrition
15
Q
longitudinal fissure
A
divides left and right hemispheres
