P1 ANATOMY Flashcards
general sensations are
pain , temperature & touch
Proprioceptive sensations are
pressure , vibration , movement & position
a specialized cell that when stimulated,
sends a sensory impulses to the CNS
sensory receptor
give at least 3 types of receptors
- free nerve endings
- merkel’s disks
- Ruffini endings
- pacinian corpuscles
- muscle spindles & golgi tendos
- Meissner’s corpuscles
mention the 5 components of CNS
- cerebrum
- cerebellum
- Diencephalon
- brainstem
- spinal cord
the Diencephalon consists of
- thalamus
- hypothalamus
the brainstem consists of
- midbrain
- pons
- medulla oblongata
type of sensation felt from muscles & joints is known as
Proprioception
type of sensation felt from skin is known as
general sensation
Slender structure continuous with the brain through the foramen magnum
spinal cord
in adults , the spinal cord ends at the level of
L1 -L2
number of cervical vertebrae & segments
Vertebrae : 7
spinal segments : 8
in children , the spinal cord ends at the level of
L2 - L3
The spinal nerve exits through the
Intervertebral foramen
state the difference between conus medullaris & cauda equina
conus medullaris : terminal end of spinal cord
cauda equina : sack of nerve roots extending below conus medullaris
