Flashcards in Comp Exam Deck (50):
What does the lateral fissure separate?
temporal lobe from frontal and parietal lobe
What does longitudinal fissure separate?
into two hemisphere
What does the central sulcus separate?
the frontal lobe from the parietal lobe
What are the lobes?
Parts of the frontal lobe:
primary motor cortex for voluntary muscle activation
controls emotions and judgments
controls motor aspects of speech
Parts of parietal lobe:
receives fibers conveying touch, proprioception, pain and temp. sensations from opposite side of body
primary sensory cortex for integration of sensation
Parts of temporal lobe:
primary auditory cortex
associative auditory cortex
Primary auditory cortex:
receives/processes auditory stimuli
Associative auditory cortex:
processes auditory stimuli
Parts of occipital lobe:
primary visual cortex
visual association cortex
Primary visual cortex:
receives/processes visual stimuli
Visual association cortex:
processes visual stimuli
What is the insula associated with and where is it locakted?
located in lateral sulcus
What is the limbic system concerned with?
instincts and emotions contributing to preservation of individual
Basic functions the limbic system is concerned with?
feeding, aggression, emotions and endocrine aspects of sexual response.
Where is white matter located?
myelinated nerve fibers located centrally
Transverse (commussural fibers)
interconnect 2 hemisphere
connect cerebral hemispheres w/other portions of brain and spinal cord
connect different portions of cerebral hemispheres, allowing cortex to function as an integrated whole
What is included in the basal ganglia?
subthalamic nucleus and substantia nigra
efferent (motor) neurons
afferent (sensory) neurons
Dorsal column (DCML)
convey proprioception, vibration, and tactile discriminatino
sensations of pain and temperature (lateral spinothalamic)
and crude touch (anterior spinothalamic)
proprioception from muscle spindles, Golgi tendon organs and touch and pressure receptors for control of voluntary movement
deep and chronic pain to reticular formation
arise from primary motor corect
arise from vestibular nucleus
control of muscle tone, antigravity muscles and postural reflexes
assist in motor function
modifies transmission of sensationm especially pain
assists in head turning and responses to visual stimuli
Autonomic nervous system:
smooth muscle, heart, glands
Divisions of ANS:
fight or flight
craniosacral, CN III, VII, IX, X, pelvic nerves
rest and digest
cardiac, pulmonary, celiac, hypogastric, pelvic
Circle of Willis:
anterior communicating artery
two anterior cerebral arteries
posterior communicating artery
connecting each posterior and middle cerebral artery
Alpha nerve fibers:
proprioception, somatic motor
Beta nerve fibers:
Gamma nerve fibers:
motor to muscle spindles
Delta nerve fibers:
pain, temperature, touch
small, myelinated, conduct less rapidly
