The ____ connects the CNS to the body, enabling communication and control.
What is the PNS?
The parts of the central nervous system are:
What are the brain and the spinal cord?
___________ conveys information and maintains homeostasis through the conduction of electrical signals and the release of chemicals called neurotransmitters.
What is the nervous system?
Are the primary type of cell that most anyone associates with the nervous system.
What are Neurons?
It is made up of a network of nerves
What is the PNS?
Peripheral Nervous System.
It's the part of the nervous system that guides your voluntary movements.
What is the somatic nervous system?
Neurotransmitters transmit one of three possible actions in their messages, depending on the specific neurotransmitter. Those are:
What are Excitatory, Inhibitory, and Modulatory?
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?
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?
The _________ system guides your voluntary movements.
What is somatic nervous?
_______system regulates the activities you do without thinking about them (involuntary movements).
.
What is the autonomic nervous?
Are known to play a supporting role for nervous tissue.
What are Glial cells, or glia?
Also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain.
What are Afferent neurons?
Based on functional classification, neurons can be (also called association or internuncial neurons) lie entirely within the brain or spinal cord.
What are Interneurons?
___________ (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?
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?
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?
Functional classification of neurons includes ________ (afferent neurons) conduct impulses from peripheral body parts into the brain or spinal cord.
What are Sensory neurons?
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?
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?
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?
____________ 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?
The Peripheral Nervous System (PNS) is divided into:
What are Somatic Nervous System (SNS) and Autonomic Nervous System (ANS)?
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?
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.
