Nervous System Concepts and Functions

This tutorial by Peter from Anatomy Zone covers the divisions and organization of the nervous system, focusing on the central nervous system (CNS) and peripheral nervous system (PNS). The CNS includes the brain and spinal cord, responsible for complex information processing. The PNS connects the CNS to peripheral structures, involving sensory and motor functions. The video also explains the functional divisions of the nervous system, including sensory and motor components, and the autonomic nervous system's subdivisions: parasympathetic, sympathetic, and enteric systems.

What are the two main divisions of the nervous system?

• Sensory and Motor

• Sympathetic and Parasympathetic

• Somatic and Autonomic

• Central and Peripheral

What are the nerves that connect to the brain called?

• Ganglia

• Plexuses

• Cranial Nerves

• Spinal Nerves

Which part of the central nervous system is responsible for complex information processing?

• Spinal Cord

• Peripheral Nervous System

• Brain

• Cranial Nerves

What is the function of the autonomic nervous system?

• Conscious perception

• Sensory information processing

• Involuntary control of the body

• Voluntary muscle control

Which subdivision of the autonomic nervous system is involved in the 'fight or flight' response?

• Parasympathetic

• Sympathetic

• Enteric

• Somatic

What does the enteric nervous system control?

• Digestive system

• Cardiac muscles

• Respiratory system

• Skeletal muscles

What is the role of the somatic nervous system?

• Conscious perception and voluntary motor responses

• Involuntary control

• Sensory information processing

• Regulation of internal environment

What is the mnemonic to remember the sensory and motor divisions?

• SAME: Sensory and Motor Exchange

• SAME: Sensory Afferent, Motor Efferent

• SAME: Sensory and Motor Equilibrium

• SAME: Sensory Efferent, Motor Afferent

What does the term 'visceral' refer to in the context of nerve fibers?

• Peripheral nerves

• Skin and muscles

• Internal organs

• Brain and spinal cord

Which of the following is NOT a special sense conveyed by cranial nerve fibers?

• Touch

• Vision

• Smell

• Taste
