First order axon not crossed
Second order axon is crossed
Thalamus- connect
Cranium instead of the canal
Trigenual nerve- 5 - 3 major roots (carnial nerve- 3?)
Perceptual – significant numbers of axon potential
Magnitude- analogy how hard pressing down on object
Spatial- receptor fields of axons (small on hand- larger on thigh) - representation
sensory
Agnosia- not thinking you don’t have disorder?
Blue- part of thalamus receives input for temperature touch an pressure to cerebral
cortex
Only exception is sense of smell- (in which it does not go through thalamus becfore
cerebral cotex)
Adogenous pain systems are mimics by opiutes.
Axon injured-
center connection- cannot be repaired
assending second axon- block pain- cant be regenerated
forbid axon regrowth- no go? Central syste doesn’t want rewiring to occur
motor neuron- peripheral nerve- loss of motor control, actively encouraged to
regrow
pheripheral regeneration!
73 feeling, 23 without good surgival realignment
nose dries out middle age
nasal receptor cells are distinct of one another – each phenotype- different order
receptor protein
bubls superior to the epithelial plate- axons up to cranial cavity with activates bulbs-
cranial nerve 1 – not really a nerve because a nerve project to pheripheral to
sensory. Franial nerve- projects visual to central nervous system- is not a true nerve.
