exam 2 Flashcards
what are the lobes of the brain?
- frontal lobe
- partial lobe
- occipital lobe
- temporal lobe
what are the main parts of the frontal lobe?
- primary motor cortex
- pre-motor cortex
- broncas area
where is the primary motor cortex located? what is its functions?
frontal lobe
- allows conscious control of precise, skilled, voluntary movements
-
where is the pre-motor cortex found? what is its functions?
frontal lobe
- controls learned repetitious, or patterned motor skills
what are the main parts of the parietal lobe?
- somatosensory cortex
- somatosensory association cortex
where is the somatosensory cortex located? what is its function?
parietal lobe
- receives sensory information from the skin, skeletal muscle and joints
- capable of spatial discrimination: identification of body region being stimulated
where is the somatosensory association cortex located? what is its function?
parietal lobe
- integrates sensory information from primary somatosensory cortex
what are the main parts of the occipital lobe?
- primary visual (striate) cortex
- visual association cortex
what is the occipital lobes main function?
its main function os the processing, integration, interpretation, etc of vision and visual stimuli
where is the primary visual (striate) cortex located? what’s its function?
Occipital lobe
- receives visual input from the retina via the optic nerve
where is the visual association cortex located? what is its function?
occipital lobe
- uses past visual experiences to interpret stimuli
what is the temporal lobes main function?
they play a role in hearing, language comprehension, memory and information retrieval
where is the primary auditory cortex found? what is its function?
temporal lobe
- interprets information from inner ear as pitch, loudness and location
what does the diencephalon house?
thalamus, hypothalamus, epithalamus
what does the thalamus do?
- Gateway to cerebral cortex
- sorts, edits, and relays information
what does the Hypothalamus do?
- Autonomic control centre for many visceral functions
- Centre for emotional centres
- Regulates body temperature, food intake, water balance and thirst
what does the epithalamus contain
contains pineal gland
what are the parts of the brainstem?
midbrain, pons, medulla oblongata
what nerves are associated with the medulla?
VIII - vestibulcochlear
X - vagus
XII - Hypoglossal
What does the cerebellum do?
- Subconsciously provides precise timing and appropriate patterns of skeletal muscle contraction
- A “blueprint” of coordinated movement is sent to the cerebral motor cortex and to brain stem nuclei
- Plays a role in word association and puzzle solving
what are the cranial nerves?
I: Oh II: Oh III: Oh IV: To V: Touch VI: And VII: Feel VIII: Very IX: Good X: Velvet XI: Ah XII: Heaven
I: Olfactory II: Optic III: Oculomotor IV: Trochlear V: Trigeminal VI: Abducens VII: Facial VIII: Vestibulocochlear IX: Glossopharyngeal X: Vagus XI: Accessory XII: Hypoglossal
what is pulmonary circulation?
from right side of heart to lungs and back to heart
what is the systemic circuit?
left side of heart to body and back to heart
