The Nervous System

the body part that is inside our head controlling how we feel, think, move, etc.

He suffered a traumatic brain injury in a car accident.

a cell that is responsible for transmitting nerve impulses between the brain and the rest of the body

Neurons transmit signals at speeds of up to 120 meters per second.

each of a group of long thread-like structures in the body that carry messages between the brain and other parts of the body, sensing things is a result of this process

a thin thread or strand, especially one that is used to make fabric or rope

The fiber of the cotton plant is spun into thread to make soft, breathable fabrics.

the inner part of the spine containing a mass of nerves that connects the brain to almost all the body parts

Damage to the spinal cord can cause permanent loss of movement or sensation.

(anatomy) a network of nerves in the abdomen and in front of the aorta that contains several ganglia

(anatomy) a mass of neurons that form a nerve center in the body outside the brain or spinal cord

related to or associated with glia or glial cells in the nervous system

a complex arrangement or network of nerve fibers or blood vessels that intersect and intertwine within the body

a neuron that acts as an intermediary between sensory neurons and motor neurons, or between other interneurons

The interneurons in the spinal cord help to relay signals from sensory neurons to motor neurons, allowing for coordinated movements.

a bundle of muscle fibers or nerve fibers bound together by connective tissue

a nerve cell that transmits signals from the central nervous system to the muscles, enabling voluntary movements

a region in the brainstem that acts as a bridge, connecting different parts of the brain and aiding in essential functions like sleep regulation and sensory-motor coordination

the bundle of nerve fibers that carries visual information from the eye to the brain

a cranial nerve that contains both sensory and motor fibers

a nerve in the upper limb that provides sensation and controls muscle movement in the hand and forearm

a sensory nerve responsible for the sense of smell

a cranial nerve responsible for controlling the movement of the eye muscles

a complex system of interconnected neurons that processes and transmits information in the body

the fourth cranial nerve responsible for controlling the movement of the superior oblique muscle of the eye

the fifth cranial nerve that provides sensory information from the face and controls the muscles responsible for chewing

a glial cell in the peripheral nervous system that forms myelin sheaths around nerve fibers

a cranial nerve responsible for controlling the muscles of facial expression

a cranial nerve responsible for hearing and balance

a cranial nerve responsible for sensory and motor functions in the head and neck region

a cranial nerve responsible for controlling certain muscles involved in head and neck movements

a cranial nerve responsible for controlling the movements of the tongue

a cranial nerve responsible for controlling the movement of the lateral rectus muscle, which enables the eye to move laterally or outward

a type of nerve cell extension that carries signals from the central nervous system to the muscles, enabling voluntary movement

a division of the autonomic nervous system responsible for regulating rest, digestion, and other essential bodily functions

a specialized cell that transmits electrical signals in the nervous system

the complex network of the brain and spinal cord that controls and coordinates bodily functions and processes

a non-neuronal cell in the nervous system that provides support and protection for neurons, helps maintain homeostasis, and participates in signaling and other important functions

a network of nerves and ganglia that connects the central nervous system to the organs, muscles, and tissues of the body, facilitating communication and control

the part of the peripheral nervous system that controls and regulates involuntary bodily functions, including heart rate, digestion, and glandular activity

a cluster of nerve cell bodies that mediates communication between the central nervous system and the organs

a network of nerves and ganglia that regulates involuntary bodily functions

a network of nerves that prepares the body for stressful or emergency situations by activating the "fight or flight" response

the part of the peripheral nervous system that is responsible for the voluntary control of body movements and the reception of external stimuli.

a type of nerve that carries signals from the central nervous system to the muscles, enabling voluntary muscle movements

a network of nerves and receptors that enables the perception of touch, temperature, pain, and body position

a bundle of nerves that emerge directly from the brain and innervate structures in the head and neck

a singular anatomical structure that carries sensory and motor signals between the spinal cord and the rest of the body

the initial segment of a spinal nerve that emerges from the spinal cord

a body part that carries sensory information from the body to the central nervous system

a nerve cell that transmits sensory information from the body to the central nervous system

a nerve fiber that carries sensory information from sensory receptors to the central nervous system

the part of the brain that processes and interprets sensory information from the body

a long, slender projection of a nerve cell that conducts electrical impulses away from the cell body towards other neurons or target cells

a key nerve responsible for transmitting signals to the muscles and skin of the thigh and leg
