Physiology of Nervous System

What are the three main functions of the nervous system?

• Sensory input, integration of data, motor output

• Sensory input, motor output, reflex actions

• Integration of data, motor output, sensory feedback

• Motor output, sensory feedback, cognitive processing

What are the five basic types of sensory receptors?

• Mechanoreceptor, Thermoreceptor, Nociceptors, Electromagnetic receptors, Chemoreceptors

• Photoreceptors, Mechanoreceptors, Thermoreceptors, Nociceptors, Chemoreceptors

• Thermoreceptors, Nociceptors, Electromagnetic receptors, Photoreceptors, Mechanoreceptors

• Nociceptors, Chemoreceptors, Mechanoreceptors, Photoreceptors, Electromagnetic receptors

What are the two major parts of the nervous system?

• Central nervous system (CNS) and peripheral nervous system (PNS)

• Sympathetic nervous system and parasympathetic nervous system

• Cerebral cortex and spinal cord

• Brain and cranial nerves

What is the role of the autonomic nervous system?

• Controls visceral functions of the body

• Regulates voluntary muscle movements

• Processes sensory information

• Coordinates reflex actions

What is a reflex arc?

• Simple connections of neurons that explain reflexive behaviors

• Complex pathways for voluntary movements

• The process of sensory integration

• The mechanism of neurotransmitter release

What neurotransmitters are primarily involved in the autonomic nervous system?

• Acetylcholine and norepinephrine

• Dopamine and serotonin

• GABA and glutamate

• Epinephrine and norepinephrine

What are the two types of cholinergic receptors?

• Muscarinic and Nicotinic

• Alpha and Beta

• Sympathetic and Parasympathetic

• Excitatory and Inhibitory
