Nervous system quick check

1 answer

Sure! Here’s a quick overview of the nervous system:

Components of the Nervous System:

  1. Central Nervous System (CNS):

    • Brain: The control center for processing and coordinating sensory information, and regulating bodily functions.
    • Spinal Cord: Connects the brain to the peripheral nervous system, transmitting messages to and from the brain.

  2. Peripheral Nervous System (PNS):

    • Somatic Nervous System: Controls voluntary movements and transmits sensory information to the CNS.
    • Autonomic Nervous System: Regulates involuntary functions (heart rate, digestion).
      • Sympathetic Nervous System: Prepares the body for stress or emergency (fight or flight).
      • Parasympathetic Nervous System: Restores the body to a state of calm (rest and digest).

Functions of the Nervous System:

  • Sensory Input: Receiving information from sensory receptors about the environment.
  • Integration: Processing and interpreting sensory input and deciding on a response.
  • Motor Output: Sending signals to muscles and glands to produce a response.

Key Cells:

  • Neurons: The basic units of the nervous system that transmit signals.
  • Glial Cells: Support cells that aid in the maintenance and functionality of neurons.

Disorders of the Nervous System:

  • Neurological Disorders: Such as Alzheimer's, Parkinson's, multiple sclerosis, and epilepsy.
  • Injuries: Such as spinal cord injuries or traumatic brain injuries.

Quick Assessment:

  1. Reflex Testing: Checking knee-jerk and other reflexes can assess neural pathways.
  2. Sensory Response: Testing touch, pain, and temperature sensation in various body parts.
  3. Motor Function: Evaluating strength, coordination, and balance.
