BIOD 152 MODULE 1 UPDATED QUESTION AND
ANSWERS 2024/2025
What is the difference between anatomy and physiology?
Anatomy focuses on the structure of the body. Physiology looks at how the body parts
function together.
How does the nervous system integrate and control the other body systems?
The nervous system receives and processes information and sends out signals to the
muscles and glands to elicit an appropriate response
How are the parts of the CNS protected?
The brain is protected by the skull and the spinal cord is protected by the vertebrae
Collections of cell bodies inside the CNS are called _____.
Nuclei
the collection of nerve axons in the CNS are called _____.
Tracts
What is included in the PNS?
cranial nerves and the spinal nerves.
Collections of cell bodies inside the PNS are called _____.
Ganglia
the collection of nerve axons in the PNS are called _____.
nerves
What are the 2 divisions of the PNS?
Efferent and Afferent
Describe the movement of nerve impulses in the PNS.
The PNS receives impulses from the sensory organs through the afferent division and
then relays signals or impulses from the CNS to muscles and glands via the motor or
efferent division.
What are the 2 divisions of the efferent division of the PNS?
Somatic and autonomic
What is controlled by the somatic systems?
controls the movements of skeletal muscles, skin, and joints
What is controlled by the autonomic nervous system?
control the glands and smooth muscles of the internal organs
What are the 2 divisions of the autonomic nervous system?
Sympathetic and parasympathetic
What is the function of the sympathetic nervous system?
prepares the body for vigorous muscular activity, stress, and emergencies
What is the function of the parasympathetic nervous system?
operates during normal situations, permits digestion, and conserves energy
Label the components of a neuron
List unusual characteristics of neurons
-Neurons do not undergo mitosis (cell division)
- Require enormous amounts of fuel
