Central Nervous System (CNS)
Components & Functions
- composed of brain + spinal cord bathed in cerebrospinal fluid (CSF)
- receives and processes sensory information and creates responses to be relayed to
muscles/glands
- the site of emotion, memory, cognition, learning
- protected by the skull & vertebrae, CSF, blood-brain barrier, meninges (dura mater, arachnoid
mater, pia mater)
Cerebrum
- largest part of the brain
- sensory & motor activities
- motor coordination
- R & L hemispheres
- 4 lobes (frontal, parietal, temporal, occipital)
Cerebellum
- beneath the cerebrum, base of the brain
- coordinates muscle movements
- controls posture
- maintains equilibrium
Brain Stem
, - composed of the midbrain, pons, and medulla
- pupillary reflexes and eye movements
- respirations
- cardiac, vasomotor functions
Spinal Cord
- extends from the brain to second lumbar vertebrae
- 2-way conduction between brain and PNS
- gray matter - neuron cell bodies
- white matter - nerve tracts
Bulla
- palpable & fluid-filled
- blister
- >5mm diameter
Pustule
- palpable & fluid-filled
- well-circumscribed lesion containing purulent exudate
Ulcer
- damaged/diminished skin surface
- loss of skin through epidermis scar formation
Fissure
- damaged/diminished skin surface
- split in all epidermal layers of skin
Excoriation
- damaged/diminished skin surface
- loss of outer skin layers from scratching/rubbing
Keloid
- augmented/increased skin surface
- augmentation of scar tissue causing significant elevation of skin surface after healing
Mongolian Spots
