The ____ connects the CNS to the body, enabling communication and control.

What is the PNS?

100

The parts of the central nervous system are:

What are the brain and the spinal cord? 

100

___________ conveys information and maintains homeostasis through the conduction of electrical signals and the release of chemicals called neurotransmitters.

What is the nervous system?

100

Are the primary type of cell that most anyone associates with the nervous system.

What are Neurons?

100

It is made up of a network of nerves

What is the PNS?

Peripheral Nervous System. 

200

It's the part of the nervous system that guides your voluntary movements.

What is the somatic nervous system?

200

Neurotransmitters transmit one of three possible actions in their messages, depending on the specific neurotransmitter. Those are:

What are Excitatory, Inhibitory, and Modulatory?


200

Are chemical messengers that your body can’t function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.

What are neurotransmitters?

200

They are the neurons that tell your body to perform an action, such as removing your hand from a hot pan.

What are efferent neurons, also called motor neurons?

200

The _________ system guides your voluntary movements.

What is somatic nervous?

300

 _______system regulates the activities you do without thinking about them (involuntary movements).


.

What is the autonomic nervous?

300

Are known to play a supporting role for nervous tissue. 

What are Glial cells, or glia?

300

Also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain.

What are Afferent neurons?

300

Based on functional classification, neurons can be (also called association or internuncial neurons) lie entirely within the brain or spinal cord.

What are Interneurons?

300

___________ (efferent neurons) are multipolar and conduct impulses out of the brain or spinal cord to effectors. They control muscle contraction and the secretions of glands.

What are motor neurons?

400

The brain is separated into 6 parts, these are:

What is frontal lobe, parietal lobe, temporal lobe, occipital lobe, the cerebellum, and the spinal cord?

400

The brain is separated into 6 parts that work together to do your daily needs

What is frontal lobe, parietal lobe, temporal lobe, occipital lobe, the cerebellum, and the spinal cord?

400

 Functional classification of neurons includes ________ (afferent neurons) conduct impulses from peripheral body parts into the brain or spinal cord.

What are Sensory neurons?

400

These neurons have only two processes, one arising from each end of the cell body. Neurons in specialized parts of the eyes, nose, and ears are this type.

What are bipolar neurons?

400

They have many processes arising from their cell bodies. Most neurons whose cell bodies lie within the brain or spinal cord are this type.


What are multipolar neurons? 

500

Neurons vary considerably in size and shape. But they have common features. They all have three distinct regions:


What are a cell body (soma), Dendrites, and Axon?

500

____________ and ________ neurons refers to different types of neurons that make up the sensory and motor divisions of the peripheral nervous system, respectively. Neurons can be classified as one or the other depending on the direction in which information travels across the nervous system

What are afferent and efferent neurons?

500

The Peripheral Nervous System (PNS) is divided into:

 What are Somatic Nervous System (SNS) and Autonomic Nervous System (ANS)?

500

Components of the PNS:

What are:

Nerves: Cranial nerves (12 pairs) and spinal nerves (31 pairs). 

•- Ganglia: Clusters of neuronal cell bodies outside the CNS. 

•- Sensory Receptors: Detect environmental changes and send signals to the CNS. 


e?

500

The PNS performs essential functions:

What are:

 

Sensory Input: Collects information from the environment.

•2. Motor Output: Relays CNS commands to muscles and glands.

•3. Homeostasis Maintenance: Regulates involuntary processes via the ANS.

•4. Reflex Arcs: Enables rapid, automatic responses to stimuli.
