Recitation Overview

• Last Recitation Date: Next Tuesday\n- Quiz Details: This recitation will include a quiz worth 20 points.
• 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
  • Medical Context: Be aware of conditions like EpiPen usage during allergic reactions;
  • Heart rate can exceed 200 bpm.
  • Recognize signs of a medical emergency.

Conclusion

• Preparation Reminder: Pay attention to the material, memorize the necessary information, and understand key physiological responses and nervous system functions in preparation for the quiz be held next Tuesday.
