|
cerebrum |
-largest part of the brain -outer layer of grey matter (cerebral cortex) and inner core of white matter -surface is highly convoluted (raised regions=gyri; groves= sulci) -conscious thoughts and intellectual functions -process somatic sensory info (GSA) -complex motor behaviors (GSE) |
|
|
what does the right part of the cerebrum control? |
left side of the body and is more artistic and has better spatial skills and understanding emotion |
|
|
what does the left part of the cerebrum control? |
right side of the body and is more analytical with math, logic, and languages |
|
|
corpus callosum |
connects right and left cerebrum hemispheres together; composed of over 200 million axons and organized into neural tracts -white matter structure allows communication between hemispheres |
|
|
diencephalon |
-located in the central core of the brain -connects the cerebrum to the brainstem -contains thalamus and hypothalamus
|
|
|
Thalamus |
sensory relay and processing center; R&L cerebellar lobes separated by 3rd ventricle |
|
|
hypothalamus |
-located inferior to thalamus -primary link between nervous system and endocrine system (connected to pituitary gland) -regulates the 4 Fs (food, sex, sleeping, temp) -control of ANS |
|
|
cerebellum |
-"little brain" -has 2 lobes connected by vermis; also has cerebellar cortex -located posteriorly, inferior to occipital lobe and posterior to the pons and medulla oblongata dn 4th ventricle -coordination of skeletal muscle and equilibrium in inner ear -damage or disease here: ataxia (no motor control) |
|
|
brainstem |
midbrain, pons, medulla oblongata |
|
|
midbrain |
-mesencephalon -connects cerebrum to the rest of the brainstem -commnicates with cerebellum -reflex center: visual and auditory -CN 3 and 4 originate here |
|
|
pons |
-transmits/relays impulses between cerebrum and cerebellum and brainstem -controls breathing -houses 4th ventricle -CN 5-8 originate here |
|
|
medulla oblongata |
-continuous with spinal courd, stops at foramen magnum -controls vital automonic functions -cardiac, vasomotor and respiratory centers (pons) -CN 8-12 originate here -gagging, coughing, sneezing, salivating, swallowing, vomiting |
