NERVOUS SYSTEM - Coggle Diagram
NERVOUS SYSTEM
control and stimulation area
cerebrum
The outer surface of the cerebrum is called the cerebral cortex. This section is the area of the brain where nerve cells make connections called synapses. The synapse is the nervous system that controls brain activity.
cerebellum
The cerebellum is responsible for controlling movement, maintaining balance, and controlling the position and coordination of body movements. This part of the brain also plays a role in controlling fine movements, such as writing and painting.
hypothalamus
the hypothalamus that first detects crucial changes in the body and responds by stimulating various glands and organs to release hormones. The hypothalamus is also the brain's intermediary for translating emotion into physical response.
nervus spinales
31 pairs of spinal nerves which are divided into five parts, namely
8 pairs of nerves in the cervical (neck),
12 pairs of nerves in the thoracic (chest),
5 pairs of nerves in the lumbar (stomach),
5 pairs of nerves in the sacral (pelvis),
1 pair of nerves again in the coccyx (coccygeal).
structure
radix
the connecting root that connects the spinal nerves to the spinal cord organs
types
anterior root
posterior root
ramus
connecting branch that connects the spinal nerves to the skin and muscles
types
anterior ramus
posterior ramus
has nerve roots that appear on the right and left. These nerve roots consist of a ventral (anterior) nerve root containing motor neurons, and a dorsal (posterior) nerve root containing sensory neurons.
encephalon
definition
The area of central nervous system that includes all higher nervous centers, enclosed within the skull and continuous with the spinal cord
part
gyrus
gyrus precentralis
gyrus poscentralis
gyrus temporalis
sulcus
sulcus centralis
sulcus lateralis
sulcus parieto occipitalis
lobe
frontal lobe
temporal lobe
parietal lobe
occipital lobe
part
mid brain
pons
diencephalon
medulla oblongata
cerebrum
cerebellum
spinal cord
general
The spinal cord, also known as the spinal cord, is a collection of nerve fibers that run along the spine, which stretches from the bottom of the brain to the lower back. This collection of tissue is relatively small, weighing only 35 grams and about 1 cm in diameter.
function
send sensory information from the body to the brain
coordinate reflexes.
send motor commands from the brain to the body
nervus craniales
The cranial nerves (cranial nerves) are twelve pairs of nerves that can be seen at the base or bottom of the brain.
the 12 pairs of nerves, 3 pairs are of sensory type (nerves I, II, VIII); 5 pairs of motor type (nerves III, IV, VI, XI, XII) and 4 pairs of combined types (nerves V, VII, IX, X).
CN I – Olfaktorius
CN II – Optikus
CN III – Okulomotor
CN IV – Troklearis
CN V – Trigeminus
CN VI – Abdusen
CN VII – Fasialis
CN VIII – Vestibulokoklearis
CN IX – Glosofaringeal
CN X – Vagus
CN XI – Aksesorius
CN XII – Hipoglossus
neuron and neuroglia
neuron
specialized cells that are responsible for generating, receiving, processing, and transmitting stimuli or impulses.
neuroglia
cells that do not transmit or generate impulses, namely neuroglia or glial cells. Glia cells function to support the activity of neurons in nervous tissue
types
in CNS
Astrocytes
Oligodendrocytes
Ependymal cells
Microglia
in PNS
Schwann cells
Satellite cells
