Nervous System Questions With Complete Solutions
Central Nervous System - ANSWER- (CNS) brain and spinal cord.
Peripheral Nervous system - ANSWER- Body Nerves that connect to the central
nervous system (brain and spinal cord). Connects the central nervous system to the
body's organs and limbs.
Autonomic Nervous System - ANSWER- Controls involuntary bodily functions (not
consciously controlled), such as breathing, the heartbeat, and digestive processes
Somatic Nervous System - ANSWER- Controls voluntary bodily functions (consciously
controlled), such as controlling skeletal muscles
2 Major Functions of Nervous System - ANSWER- 1. Sensory Reception-end of
peripheral neurons monitor conditions( light,sound,temperature)
2. Integrative Functions- Sensory messages that get sent repeatedly get remembered
"motor functions" (subconscious actions)
Order of Stimulus (from sensory to effector) - ANSWER- 1. Stimuli: physical or chemical
signal (ex. hot room)
2. Nerve impulse (ex. sends signal to brain)
3. Effectors: muscle & glands react (ex. sweat glands start sweating)
Stimulus - ANSWER- Things that initiate nerve impulses (ex. hot room)
Effector - ANSWER- Response (ex. Sweating)
Motor Functions - ANSWER- Complex muscle-and-nerve acts that produce movement
(walking, writing, typing running etc.)
, "Electrochemical" - ANSWER- A nerve impulse is partially electric (change in
polarity/charge) and partially chemical (neurotransmitters)
Synapse - ANSWER- Where the nerve impulse is sent (connection of 2 neurons) .
Action Potential changes the charge of the synapse (causes electricity) and
Neurotransmitters are sent.
Myelin Sheath - ANSWER- Covering of Schwann Cells, Speeds up nerve impulses.
Axon - ANSWER- The long threadlike part of a nerve cell that carry the nerve impulse
Dendrites - ANSWER- Branch like extensions on a neuron that GET signals and
connect to the synapse
Neurotransmitters - ANSWER- Chemicals that transmit signals across a synapse from
one neuron to another 'target' neuron
Multipolar Neuron - ANSWER- Most of the brain/spinal cord & is mylinated
Bipolar Neuron - ANSWER- Found in eyes, nose, and ears
Classified as an "Interneuron": connects PNS to CNS
Unipolar Neuron - ANSWER- Accepts Sensory messages (feelings & senses)
Found outside of the brain and spinal cord
Sensory Neuron - ANSWER- Nerve cells that transmit sensory information (sight, smell,
sound etc.)
Central Nervous System - ANSWER- (CNS) brain and spinal cord.
