  • Preparation: Students are given one week to memorize 16 words.

Quiz Structure

  • Questions: Only 10 questions will be selected from the 16 words provided.
  • Focus Topic: The quiz will pertain to the sacral plexus.

The Sacral Plexus

  • Levels: Memorize the levels related to the sacral plexus:
    • S2, S3, S4 are essential.
    • Mnemonic: “S 2, 3, 4 keeps the feces off the floor.”
    • This signifies the sacral plexus's function in bowel control.

Autonomic Nervous System (ANS)

  • Definition: The ANS is the automatic section of the motor subdivision of the nervous system.
  • Functions: It controls involuntary functions, including:
    • Cardiac and smooth muscle regulation
    • Glandular activity
  • Subdivision: The ANS has two main subdivisions:
    • Sympathetic: Related to 'fight or flight' responses.
    • Parasympathetic: Rest and digest functions.

Parasympathetic Cranial Nerves

  • Important Cranial Nerves (Parasympathetic):
    • Cranial Nerves: 3 (Oculomotor), 7 (Facial), 9 (Glossopharyngeal), 10 (Vagus)
    • Significance: Understanding these nerves is crucial for recognizing how the parasympathetic system operates.

Sympathetic Response

  • Fight or Flight Mechanism:
    • Example: Reacting to an unexpected event (like someone bursting through a door).
    • Physiological Response: Immediate changes such as:
    • Increased heart rate
    • Elevated blood pressure

    • Heart rate can exceed 200 bpm.
