Brain quiz Flashcards
Parietal lobe
Receives & associates somatosensory information
Frontal lobe
Sends motor output
Occipital lobe
Receives visual information
Temporal lobe
Receives auditory information
Brain functions
Maintain homeostasis through :
Sensory input & motor output
Makes decisions-interpret
Integrates & stores new info
What are the 4 parts of the brain?
Cerebrum
Cerebellum
Diencephalon
Brain stem
Outward folds (bumps) are called
Gyri (gyrus)
Shallow grooves are called
Sulci (Sulcus)
Deepest grooves called
Fissures
Longitudinal fissure
Separates cerebral hemispheres (left & right)
Cerebrum
Controls all sensory & motor functions, thought processes, and memories
What are all the cranial nerves ?
Olfactory Optic Oculomotor Trochlear Trigeminal Abducens Facial Vestibulocochlear Glossopharyngeal Vagus Accessory Hypoglossal
How to remember cranial nerves by name?
Oh Once One Takes The Anatomy Final Very Good Vacations Are Happening
How to remember function of cranial nerves?
Some Say Money Matters But My Brother Says Big Brains Matter More
Diencephalon consists of
Thalamus
Hypothalamus
Pineal gland
Brain stem consists of
Medulla oblongata
Pons
Midbrain
Cerebellum function (2)
Evaluates how well movements initiated by motor area in cerebrum are being carried out to make complex skilled movements
Regulates posture & balance
Limbic system
Includes several area of brain
“Emotional brain”
Function- mediates emotional responses (pain, pleasure, docility, affection, & anger)
Involved in smell & memory
Order of the brain stem parts?
Midbrain 1
Pons 2
Medulla 3
Function of thalamus (4)
Major relay station for sensory impulses in the primary sensory areas of cerebral cortex
- transmits info from cerebellum to primary motor areas of cerebral cortex
- relays impulses btwn diff. Areas of cerebrum
- involved in movement control, emotions, learning, memory, & cognition
Function of hypothalamus (5)
Controls autonomic NS located inferior to thalamus Regulate emotional & behavioral patterns Regulate eating & drinking Control body temp Regulate circadian rhythm
Pineal gland function (2)
Secretes melatonin-promotes sleep
Sets body’s biological clock
Midbrain function (4)
Relays motor impulses from cerebral cortex to pins
Relays sensory impulses from spinal cord to thalamus
Coordinates movements of head, eyes, & trunk in response to visual & auditory stimuli
Helps coordinate voluntary body movements
Pons function (2)
Relays impulses btwn cerebral cortex & cerebellum & midbrain & medulla
Helps controls breathing rhythms
Medulla function (3)
Relays motor & sensory impulses btwn other brain parts & spinal cord
Regulates heartbeat, breathing, blood vessel diameter
Coordinates swallowing, vomiting, coughing, sneezing, & hiccups
