Q1. What are the main divisions of the nervous system?

Background

Topic: Organization of the Nervous System

This question tests your understanding of how the nervous system is structurally and functionally divided, which is foundational for anatomy and physiology (ANP).

Key Terms:

  • Central Nervous System (CNS)

  • Peripheral Nervous System (PNS)

  • Autonomic Nervous System (ANS)

  • Somatic Nervous System

Step-by-Step Guidance

  1. Start by identifying the two broadest divisions: CNS and PNS.

  2. Within the PNS, determine the two main functional subdivisions: somatic and autonomic.

  3. For the ANS, further divide it into sympathetic and parasympathetic branches.

Q2. What are the divisions of the Autonomic Nervous System (ANS), and which neurons are myelinated or unmyelinated, and short or long?

Background

Topic: Autonomic Nervous System Structure

This question focuses on the structural differences between sympathetic and parasympathetic divisions, including neuron characteristics.

Key Terms:

  • Sympathetic Division

  • Parasympathetic Division

  • Preganglionic Neuron

Step-by-Step Guidance

  1. Identify the two main divisions of the ANS.

  2. For each division, determine whether the preganglionic and postganglionic neurons are myelinated or unmyelinated.

  3. Compare the relative lengths (short or long) of preganglionic and postganglionic neurons in each division.

Q3. What neurotransmitters are associated with the divisions of the nervous system?

Background

Topic: Neurotransmitters in Nervous System Function

This question tests your knowledge of which neurotransmitters are released by different divisions of the nervous system.

Key Terms:

Step-by-Step Guidance

  1. List the main neurotransmitters for the CNS and PNS.

  2. Identify which neurotransmitters are used by the sympathetic and parasympathetic divisions of the ANS.

  3. Note any exceptions or special cases (e.g., adrenal medulla secretion).

Q4. What are the receptors for the neurotransmitters associated with the divisions of the nervous system, and are the neurotransmitters excitatory or inhibitory?

Background

Topic: Neurotransmitter Receptors and Effects

This question examines your understanding of how neurotransmitters interact with their receptors and the resulting effects.

Key Terms:

  • Nicotinic and Muscarinic Receptors (for ACh)

  • Adrenergic Receptors (for NE and Epi)

  • Excitatory vs. Inhibitory Effects

Step-by-Step Guidance

  1. Identify the main receptor types for each neurotransmitter in the ANS.

  2. Determine which neurotransmitters are generally excitatory or inhibitory at each receptor type.

  3. Consider how the effect may vary depending on the target tissue and receptor subtype.

Q5. What are the types of glial cells, their functions, and are they associated with the CNS or PNS?

Background

Topic: Neuroglia (Glial Cells)

This question tests your ability to identify glial cell types, their roles, and their locations in the nervous system.

Key Terms:

  • Astrocytes, Oligodendrocytes, Microglia, Ependymal Cells (CNS)

  • Schwann Cells, Satellite Cells (PNS)

Step-by-Step Guidance

  1. List the main glial cell types found in the CNS and PNS.

  2. For each cell type, briefly describe its primary function.

  3. Match each cell type to its respective nervous system division (CNS or PNS).

Q6. What are the stages of the action potential, how do they relate to membrane potential, and to the flow of ions?

Background

Topic: Action Potential Physiology

This question tests your understanding of the sequence of events during an action potential and the ionic movements involved.

Key Terms and Concepts:

  • Resting Membrane Potential

  • Depolarization

  • Repolarization

  • Hyperpolarization

  • Sodium (Na+) and Potassium (K+) Channels

Step-by-Step Guidance

Key Terms:

  • Frontal Lobe

  • Parietal Lobe

  • Temporal Lobe

  • Occipital Lobe

Step-by-Step Guidance

  1. List each lobe of the cerebrum.

  2. For each lobe, identify its main functional roles (e.g., motor, sensory, auditory, visual).

  3. Consider examples of what might happen if each lobe is damaged.

Q8. How is the pituitary gland connected and regulated by the hypothalamus?

Background

Topic: Hypothalamic-Pituitary Axis

This question tests your understanding of the anatomical and functional relationship between the hypothalamus and pituitary gland.
