Anatomy Exam 4 part 3 Flashcards
What is the difference between general sensory pathways that stop in the Cortex and ones that dont
If they dont reach the Cortex they are reflexes
What is the name given to general sensory receptors found on organs
Introceptors
Where is the visceral sensory information processed
Solitary Nucleus
Where are Upper motor neurons found?
Lower motor neurons?
upper- Cerebral Cortex
lower- Spinal cord
What two general groups of muscles are controlled by the somatic nervous system?
Skeletal and Smooth
What controls skeletal muscles
Pyramidal system
where do most pathways of the Conspinal pathway cross?
Premietal Decusation
What two pathways of the somatic nervous system do not originate in the cerebral cortex?
Medial and lateral
What do these do? Receptor Classes:
1. Thermoreceptors
- Nociceptors
- Mechanoreceptors
- Temperature
- Pain Receptors
- Touch(hair), Pressure, Position
What do these do? Mechrioceptors 1 Tactile Receptors 2 Baroceptors 3 Proprioceptors
Tactile- Touch(hair)
Baroceptors- Pressure
Proprioceptors- Joint Position
What are the two primary division of ANS and what do they do
Sympathetic- Fight/Flight
Parasympathetic- Rest/Digest
What is the purpose of the Autonomic nervous system?
Homeostasis Subconscious (VISCERAL) heartbeat
How many neurons does the Somatic nervous system have? The Autonomic?
Somatic- 2 neurons
Autonomic- 3 neurons
Which divison of the ANS is organized into bilateral chains of ganglia that lie alongside the vertebral column
Sympathetic
Which division of ANS has ganglia closer to the EFFECTOR organ
Parasympathetic
