BRAIN STRUCTURES/SYSTEMS
forms motor system with other structures incorporating sensory feedback & adjusting movements with motor plans
Basal Ganglia
-Controls head movements & gaze stabilization (vestibul-ocular reflex)
-*VITAL Fx: CARDIAC, RESPIRATORY, VASOMOTOR CENTERS
Medulla Oblongata
Motor control & Muscle tone
substantia nigra (MIDBRAIN)
(integration of sensation)
Receives fibers for touch, proprioception, pain, & temp. from OPPOSITE side of body
PARIETAL (top-back portion of brain)
Wernicke's Area is located where?
TEMPORAL lobes (sides)
Cerebellum
-equilibrium & regulation of muscle tone
-maintenance of posture & voluntary movement control
-ensures smooth coordination of voluntary movements (accurate force, direction, & degree of movement)
Cardiac, Respiratory, and Vasomotor Centers
Medulla Oblongata (BRAIN STEM)
Vision + Visual reflexes
superior colliculus (MIDBRAIN)
receives/processes VISUAL stimuli
OCCIPITAL (back end portion of brain)
Wernicke's area is responsible for what?
language comprehension
(temporal lobes)
(aggression, emotions, sexual response, & long-term memory)
LIMBIC SYSTEM
Allows passage of sensory & motor info. modulating pain & controlling arousal
Pons
Hearing + Auditory reflexes
inferior colliculus (MIDBRAIN)
receives/processes AUDITORY stimuli
WERNICKE'S area: written & spoken language comprehension
TEMPORAL (lower side portion of brain)
Broca's area is responsible for what?
In addition to serving a role in speech production, the Broca area also is involved in language comprehension, in motor-related activities associated with hand movements, and in sensorimotor learning and integration.
(frontal lobe)
forms motor system with other structures incorporating sensory feedback & adjusting movements with motor plans
BASAL GANGLIA
Contains ascending (sensory) + descending (motor) tracts that run to/from cerebrum & pons
cerebral peduncles (MIDBRAIN)
mesencephalon
Midbrain (BRAIN STEM)
Broca's area
FRONTAL
If a patient cannot feel some degree of temperature, pain, touch, or proprioception on the left side of their body, they likely experienced injury to what area of the brain?
Right Parietal Lobe
Diencephalon
THALAMUS: relay sensory info. to the cerebral cortex, relay motor info. from cerebellum to motor cortex, integrate visceral & somatic functions
Coordination & CN nuclei: Oculomotor & Trochlear
red nucleus (MIDBRAIN)
1. superior colliculus
2. inferior colliculus
1. vision + visual reflexes
2. hearing + auditory reflexes
MIDBRAIN-->BRAIN STEM
voluntary muscle activation
emotions, judgment, cognitive *fx (ideation & abstraction)
*planning motor movements
*BROCA'S area=language comprehension
FRONTAL (front portion of brain)
