Lecture 22- The Brain Flashcards
The vertebrate brain is ____
regionally specialized
forebrain
- processing of olfactory input
- regulation of sleep
- learning
- any complex processing
midbrain
coordinates routing of sensory input
Hindbrain
- involuntary activities
- coordinates motor activities
Size differences in the brain between species reflect the relative importance of ___
particular brain function
Cerebrum functions
- skeletal muscle contraction
- center for learning
- emotion
- memory
- perception
What is the cerebrum
largest part of the brain (main areas)
Cerebrum components
- cerebral cortex
- hippocampus
- corpus callosum
Cerebral cortex
outer layer of the cerebrum
cerebral cortex funciton
- perception
- voluntary movement
- learning
Hippocampus position
in the middle of the temporal lobe
hippocampus funciton
short term memory
What is the corpus callosum
a thick band of axons
corpus callosum function
enables right and left cerebral cortices to communicate
Cerebellum
coordinates movement and balance helps in learning and remembering motor skills
Diencephalon major components
- Thalamus
- Hypothalamus
Thalamus function
main input center for sensory information going to the cerebrum
hypothalamus function
control center that includes the
- body’s thermostat
- central biological clock
Brainstem components
- Midbrain
- Pons
- Medulla oblongata
Midbrain function
receives and integrates sensory information and sends it to specific regions of the brain
pons function
transfer information between the PNS and the midbrain and forebrain
Medulla oblongata function
- transfer information between the PNS and the midbrain and forebrain
- breathing, heart and blood vessel activity, swallowing, vomiting, and digestion
