Somatic vs Autonomic
What two different pathways does the somatic nervous system have?
Afferent and Efferent
What is the function of the afferent pathway
Transports sensory information to the brain (Afferent=Arrives at brain)
What body parts are the CNS made up of?
Brain and spinal cord
What is the primary function of the occipital lobe?
Visual processing
What is the temporal lobe's key role?
Hearing and language comprehension
List what the somatic nervous system controls
Voluntary movements of skeletal muscles
What is the function of the Efferent pathways
Carries motor commands from the brain to the muscles (Efferent=Exits the brain)
What is the function of the spinal cord?
Transmit nerve signals between the brain and the rest of the body.
What part of the brain is last to develop?
Frontal lobe
What is the function of the cerebellum?
Coordinating and regulating movement
List two things the autonomic nervous system controls
Eyes, heart, circulatory system, lungs, intestine, colon liver, pancreas, urinary tract and reproductive system (Almost all of your major organs)
What is the role of the reflex arc?
A pathway that controls a reflex action and involuntary and automatic response to stimulus. Located in the spinal cord.
The peripheral nervous system is divided into two systems. Name the two
Autonomic (involuntary) and Somatic (voluntary)
What is the main function of the brain stem?
Regulates vital bodily functions necessary for survival (Breathing, HR, BP, Digestion, Sleep cycles, etc)
Where is the cerebellum located?
At the back of the head, below the cerebrum and above the brainstem.
The autonomic nervous system has two divisions. Name them.
Sympathetic (fight or flight) and Parasympathetic (Rest and digest)
What does the receptor do?
Detects stimulus
Which system controls the decision making?
Central nervous system
Name the three main parts of the brain
Cerebellum, cerebrum and brain stem
Define the parietal lobe function?
What is an example of an involuntary muscle?
Heart, Gastrointestinal muscles, blood vessels, lungs, pupils, etc.
What is the integration center? (or Processing center)
The spinal cord or brainstem part of the reflex arc where the sensory information is processed and a motor response is initiated.
What type of cell in the CNS is responsible for the transmission of electrical signals?
Neurons
Name the four lobes of the cerebrum
Frontal lobe, occipital lobe, parietal lobe and temporal lobe
What are the differences in function between the frontal and parietal lobe?
Frontal lobe handles executive functions like decision-making, planning, and voluntary movement, while the parietal lobe is primarily responsible for processing sensory information such as touch, pressure and temp.
