Week 10 UNE BIOL 1011: Final Exam
Questions and Answers.
List and explain the general characteristics of the nervous system. - Answer Requires
Information
- From receptors and senses
Integrates Information
- Interpreting information from multiple sources
Rapid Response
- Motor output
- Potential to receive, integrate, and respond within 1/10th of a second
Compare the nervous system to the hormone system in terms of speed and length of action. -
Answer Nervous System
- Speed: Very fast (milliseconds to seconds)
- Duration: Short-lived; stops when stimulus ends
Hormone (Endocrine) System
- Speed: Slower (seconds to hours or days)
- Duration: Long-lasting; effects persist even after stimulus ends
CNS - Answer Brain and spinal cord
Information processing
React to sensory information
Integrate
Issue motor commands
Interneurons: Develop response and send it back via motor neurons
PNS - Answer Cranial and spinal nerves
Afferent neurons: Sensory
Efferent neurons: Motor commands
, Afferent - Answer Carry sensory information from the body's periphery (like skin, muscles,
etc.) towards the central nervous system (brain and spinal cord).
Efferent - Answer Carry motor commands from the central nervous system to muscles and
glands, causing them to contract or secrete
Somatic Motor System - Answer Mostly conscious control
Skeletal muscles
Voluntary
Autonomic Motor System - Answer Two different groups of neurons that work in opposition
Unconscious
Smooth muscles, cardiac muscle, glands
Coordinate body responses
Work in Opposition
Involuntary
Sympathetic Nervous System - Answer Alertness
Arousal
Fight or flight
Neurotransmitters
- Epinephrine
- Norepinephrine
Parasympathetic Nervous System - Answer Relaxation
Normal body functions
Neurotransmitter
- Acetylcholine
Dendrites - Answer Afferent (information coming in)
Cell Body (Soma) - Answer Nucleus
Other organelles
Axon - Answer Efferent (information going out)
