Jul 11, 2024 · Learn about the anatomy, function, and disorders of the central nervous system, which consists of the brain and spinal cord. Find out how nerve impulses are transmitted by synapses and gap junctions, and how the central nervous system is protected by meninges and cerebrospinal fluid.
Jul 4, 2024 · nervous system, organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs. Follow the electrical and chemical changes undergone to transmit an impulse through the human nervous system.
Jul 19, 2024 · The brain and spinal cord form the control center known as the central nervous system (CNS), where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions inside and outside of the body and send this information to the CNS.

2 days ago · The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum.
Jul 19, 2024 · The sensory organs of the head use the cranial nerves for signal transmission, including smell (olfactory nerve), vision (optic, oculomotor, abducens, and trochlear nerves), taste (facial and glossopharyngeal nerves) and hearing (vestibulocochlear nerve).
2 days ago · The cranial nerves are considered components of the peripheral nervous system (PNS), although on a structural level the olfactory (I), optic (II), and trigeminal (V) nerves are more accurately considered part of the central nervous system (CNS).
