|
Frontal Lobe. |
- responsible for cognition (intelligence, problem solving, STM), motor planning, working memory, math calculations.
- has Broca's area: controls motor aspects of speech. Frontal Lobe responsible for expressive language. - has Prefrontal lobe: responsible for executive functioning (organization, planning, sequencing, motivation, etc), self insight, regulation of emotions. |
|
|
Parietal Lobe.
|
responsible for sensory detection, perception, and interpretation (touch, proprioceptive, pain, temperature sensations from opposite sides of the body)
|
|
|
Temporal Lobe.
|
processes auditory stimuli, LTM, has Wernicke's area: language comprehension.
|
|
|
Occipital Lobe.
|
interpretation of visual stimuli.
|
|
|
Insula (lobe).
|
perceptual processing of visceral functions (gustatory)
|
|
|
Limbic system.
|
- oldest part of brain
- deals with basic functions = feeding, aggression, raw emotions (associated with LTM), endocrine aspect of sexual response |
|
|
What is included in the diencephalon?
|
Thalamus and Hypothalamus
|
|
|
Thalamus.
|
gateway to the cortex, relays sensory/motor information to the cortex.
|
|
|
Hypothalamus
|
Regulates ANS and neuroendocrine system, maintains body homeostasis (body temperature, hunger, water balance, sleep/wake cycles, emotion, sexual behavior)
|
|
|
What is included in the brain stem?
|
(in order downwards) Midbrain, Pons, Medulla
|
|
|
Midbrain.
|
role in automatic reflexive behaviors dealing with vision and audition.
|
|
|
Pons.
|
- deals with the relay system among the spinal cord, cerebellum, and cerebrum.
- mediates motor information on an unconscious level. |
|
|
Medulla.
|
- carries descending motor messages from cerebrum to SC.
- carries ascending sensory messages from SC to cerebrum. |
|
|
The brain stem controls what functions?
|
Vegetative functions: respiration, cough/gag reflex, pupillary response, swallowing reflex
|
|
|
Cerebellum.
|
- equilibrium, regulation of muscle tone
- maintains posture, voluntary movement control - smooth coordination of movements |
|
|
Autonomic Nervous System includes what?
|
SNS
PNS |
|
|
Sympathetic Nervous System.
|
Prepares the body for fight/flight
- emergency responses, increases HR/BP, constricts peripheral blood vessels and redistributes blood, inhibits peristalsis. |
|
|
Parasympathetic Nervous System.
|
Conserves and restores homeostasis, decreases HR/BP, increases peristalsis and glandular activity.
|
|
|
Cerebral Spinal Fluid.
|
- Protects the brain (acts as a shock absorber).
- Deals with the exchange of nutrients and waste (keeps bad things out) |
|
|
Hydrocephalus.
|
- A build-up of pressure and fluid that results in compression of neural tissue and enlargement of the ventricles.
- can occur in infants and adults Tx: Infant (cause is blockage): shunt (tube) that bypasses blockage Infant (excessive CSF): shunt to drain excess CSF to abdomen Adult: surgical shunt to abdomen to drain excess. |
|
|
Nerve Distribution to the Hand.
