Study Notes
Nervous System - Multiple Choice Questions
-
Nervous System Function: The nervous system receives sensory input, integrates stimuli with reactions, triggers motor responses, and controls motor output.
-
Central Nervous System (CNS): Composed of the brain and spinal cord.
-
Peripheral Nervous System (PNS): Composed of spinal nerves and cranial nerves.
-
Nerve Impulse Transmission (Neuron):
- Nerve impulses begin at a neuron's dendrites.
- Impulses travel through the neuron's cell body.
- Impulses move along the axon.
- The tiny space between neurons is called a synapse.
- Neurotransmitters carry the impulses across the synapse.
-
Protective Brain Structures: A cushion of fluid (cerebrospinal fluid) and the bony skull. In addition, the meninges, which are membranes, also protect the brain.
-
Brain Function:
- Cerebellum: Coordinates voluntary movements and balance.
- Brain Stem: Controls unconscious bodily functions.
- Cerebrum: Responsible for higher-level functions like conscious thought and voluntary actions.
- Cranial Nerves: Part of the PNS, these nerves transmit sensory and motor information to and from the brain, respectively.
