Chapter 13 Region With Function Flashcards
Medulla oblongata
Cardiovascular center (regulation of heart rate and blood vessel diameter)
Respiratory center
Pyramidal descussation (cross over of motor tracts)
pons
Respiratory center
Cerebellum
Balance and coordination
Substantia nigra
Dopamine production
Red nucleus
Control of back muscles (erector spinal group)
Superior colliculi
Visual reflexes
Inferior colliculi
Auditory reflexes
Thalamus
Relays sensory impulses from receptors in various parts of the body to the cerebral cortex
Pineal gland
Melatonin production
Hypothalamus
Thirst center
Master control of endocrine and autonomic NS
Production of ADH and oxytocin
Control of food intake
Amygdala
Expression of emotion, control of behavioral activities, moods
Caudate nucleus
Helps produce pattern and rhythm of walking movements
Corpus callosum
Connects the left and right sides of the brain allowing for communication between both hemispheres.
Primary sensory cortex
Makes you aware of a sensation
Association areas
Give meaning to/make associations with a sensation (recognition)
Motor areas
Allow you to act upon a sensation
Occipital cortex
Primary visual cortex
Visual association area
temporal cortex
Primary auditory center and association area
Olfactory cortex-smell
Parietal lobe with postcentral gyrus
Somatosensory, sensory homunculus
Primary sensory cortex (general senses: touch, pressure, pain, temperature)
Association area: allows to recognize object, distinguish size and shape solely by touch
Precentral gyrus
Primary motor cortex: voluntary control of the skeletal muscles. Motor homunculus
prefrontal cortex
Intelligence, social behavior, judgement, problem solving
insular cortex
Gustatory cortex- taste
Broca’s area
Motor speech area
Located only in the left hemisphere
Allow you to act upon a sensation
Wernicke’s area
Located only in the left hemisphere
Language comprehension
