Cards

Term
Medulla
Definition
contains BP regulatory center that controls HR, force of contraction and blood flow distribution, also contains ventilator rythmicity center
Term
Broca's Area
Definition
lies in the frontal lobe, generates motor programs for muscles used to speak
Term
Primary Sensory Cortex
Definition
located in the parietal lobe, just after the central sulcus, integrates sensory information for touch, pressure, vibration, pain & temperature
Term
Midbrain
Definition
contains reticular activating system or RAS, which extends throughout the brainstem and the cerebral cortex and determines one's state of consciousness
Term
Hypothalamus
Definition
major control center for autonomic/endocrine function. operating through pituitary gland, it regulates growth, metabolism, reproduction, and stress responses.  also plays role in thermo-regulation, food and water intake, sleep, memory and emotion
Term
Primary motor cortex
Definition
located in frontal lobe just before the central sulcus; initiates conscious motor muscle activity
Term
Cerebellum
Definition
adjusts postural muscles of the body and fine-tunes or coordinates all motor or muscle activity
Term
Primary visual cortex
Definition
lies in posterior portion of the occipital lobe, processes visual information
Term
Pituitary Gland
Definition
anterior lobe secretes 6 principal hormones that stimulate endocrine cells elsewhere to release their own hormones, whereas it's posterior lobe stores/releases two hormones produce by the hypothalamus
Term
Inferior Colliculi
Definition
part of the auditory pathway that controls reflex movements of head, neck and trunk in reponse to auditory stimuli (noise)
Term
Pineal Gland
Definition
Collaterals from visual pathways to this gland affect rate of melatonin production, which may affect sleep patterns and help maintain basic circadian (24-hour) rhythms
Term
Superior Colliculi
Definition
part of the visual pathway that controls relfex movements of eyes, head and neck in response to visual stimuli (such as bright light)
Term
Wernicke's Area
Definition
located in posterior part of upper temporal lobe and the inferior part of parietal lobe in the left cerebral hemisphere: integrates written or spoken language
Term
Primary auditory Cortex
Definition
lies in temporal lobe, processes auditory information
Term
Thalamus
Definition
gateway for all sensory information, relays sensory info to appropriate area of the brain, heavily connected to limbic system (emotion and memory)
Term
Prefrontal Cortex
Definition
lies in frontal lobe, performs abstract intellectual functions, enabling us to think about, plan, and execute appropriate behaviors
Term
Pons
Definition
contains respiratory centers that modify the activity of the respiratory rhythmicity center
