Body - Nervsystemet

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

hjärna

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

neuron

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

nerv

any strand of muscle or nervous tissues

muskelfiber

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

ryggmärg

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

axon

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

solplexus

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

ganglion

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

glial

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

plexus

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

interneuron

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

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

trochleär nerv

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

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

glossopharyngeal nerv

a cranial nerve that plays a vital role in regulating various bodily functions, including heart rate, digestion, and respiratory control

vagusnerv

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

accessorisk nerv

a cranial nerve responsible for controlling the movements of the tongue

hypoglossusnerven

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

abducensnerven

a type of neuron that has a single projection, or process, that branches into two directions

unipolär neuron

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

motorisk nervfiber

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

parasympatiska nervsystemet

a specialized cell that transmits electrical signals in the nervous system

nervcell

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

centrala nervsystemet

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

glia cell

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

perifera nervsystemet

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

autonoma nervsystemet

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

autonomt ganglion

a network of nerves and ganglia that regulates involuntary bodily functions

autonom plexus

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

sympatiska nervsystemet

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

somatiska nervsystemet

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

motorisk nerv

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

somatiskt sensoriskt system

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

kranial nerv

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

ryggmärgsnerv

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

spinal nervrot

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

sensorisk nerv

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

sensorisk neuron

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

sensorfiber

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

sensorisk cortex

a type of neuron that has many processes or projections (dendrites) arising from its cell body, and a single axon that extends away from the cell body
