Anatomy Flashcards
Highly complex system that includes brain, spinal cord, nerves
Nervous System
3 major division of nervous system
CNS
PNS
ANS
Largest part of the brain
Cerebrum
2 sections of the brain are called as
Cerebral Hemisphere
Outermost layer of the brain
Cerebral cortex
2 sections of the cerebral hemisphere
Left Hemisphere
Right Hemisphere
Raised convulsions (humps sa brain)
Gyri
Shallow grooves
Sulci
Deep furrows (nagdidivide ng brain into left and right hemisphere)
Fissures
Frontal lobe
Personality
Intelligence
Motor Activity
Speech (Broca’s aphasia)
the output of spontaneous speech is markedly diminished and there is a loss of normal grammatical structure. Specifically, small linking words, conjunctions, such as and, or, and but, and the use of prepositions are lost.
Broca’s aphasia
Temporal lobe
Smelling
Hearing
Taste
Speech (Wernicke’s)
language disorder that makes it hard for you to understand words and communicate.
wernicke’s aphasia
Parietal lobe
Tactile sensation
How to assess tactile sensation
(0,1,2)
2= may nafifeel if nilagyan ng pressure ung tuktok ng ulo
1= need more pressure
0= wala nafifeel
Occipital lobe
Vision
Coordination
Balance
Test for occipital lobe
Finger to nose test
Heel to toe
Role in the process of memory (long term to short term memory)
Hippocampus
composed of thalamus and hypothalamus
Diencephalon
ano under kay Thalamus
Sensory
Relay Station
ano under kay hypothalamus
Thermoregulation
Emotions
Midbrain
Motor
Relay Station
aling part ng brain stem ang nag uurge na maginhale or exhale
midbrain
aling part ng brain stem ang nag uurge na maginhale if maraming carbond dioxide sa body and primary for respiration
Medulla
secondary for respiration and nagcocommand kung gano kalalalim or kababaw ung paghinga
PONS
little brain and resides under occipital lobe
cerebellum
alternate moving of pslms, lack of coordination
dysdiachokinesia
Under cerebellum
Posture
Balance
Coordination
How to assess the function of cerebellum
Rhomberg’s Test - eyes, closed, spread ang legs, raised ang arms sidewards
Finger-nise test
Heel to toe
one way to assess your drunkard’s walk or ataxic gait
Heel to toe
Composed of ascending and descending pathway
Center for reflex acts
spinal cord
sensory fibers that carries impulses to the brain
ascending fibers (afferent fibers)
motor fibers that carries impulses to the brain
descending pathway (efferent fibers)
Pathophysiology of pathways
ascending fibers - thalamus - hypothalamus - descending pathway
composed of 12 pairs of cranial nerve and 31 pairs of spinal nerves
provides pathway to cns
peripheral nervous system
