SENSORY PATHWAY
Stimulus Receptors
•Internal •Sense organs Electrical Affarent CNS
•External •Transducers potential pathway integration
•Energy source
There is a control mechanism in all the physiological mechanisms:
1. Sensory pathways begin with a stimulus.
2. Sense organs (receptors) pick up information and send it with the afferent pathway to the CNS
3. Integration will occur
4. There will be a response
Sensory stimuli
Special senses Somatic senses
Vision Touch
Hearing Temperature
Taste Pain
Smell Proprioception
Equilibrium

UNIT 4.2 – SOMATIC SENSES
SOMATIC SENSORY SYSTEM
2 tracts:
Spinothalamic tract (anteriorlateral tract) Spinocortical tract (posterior tract)
• Nociception (sensing pain) • Proprioception (awareness of body position /movement)
• Coarse touch • Fine touch
• Temperature • Vibration
This pathway crosses the midline in the spinal cord This pathway crosses the midline of the medulla
Spinocortical tract
Spinothalamic tract
NEUROBALANCE
Balance of brain is essential to overall wellbeing and performance. Once the brain is balanced, the body follows
Brainwave optimization:
