The nervous system is made up of the brain, spinal cord, and several different kinds of nerves that are found throughout the body. These create complex circuits through which animals experience and respond to sensations. A familiar type of nervous system circuit is a reflex.
Sensory neurons carry information from the body to the spinal cord or brain stem, and then on to the cerebellum, brain stem, and cerebrum for interpretation. Sensory information includes sensations of pain, position, touch, temperature, taste, hearing, balance, vision, and smell.
26 sie 2016 · A sensory system is characterized by a peripheral afferent neuron with a dendritic zone that is commonly modified to form a receptor organ; an axon that courses into the gray matter of the central nervous system (CNS); a cell body in a ganglion of the peripheral nervous system; and a centrally located relay nucleus and tract that courses ...
16 lip 2022 · The dog optic nerve is sensory, whereas the oculomotor is a motor type of nerve. You will see the attachment of the optic nerve to the optic chiasma of the brain. It passes from the optic foramen of the dog.
26 lip 2023 · Composed of different regions, each with its unique functions, the dog’s brain is responsible for processing sensory information, initiating movements, and regulating bodily functions. By examining the structure and function of the dog’s brain, we can gain valuable insights into their cognitive abilities and behavior.
Sensory, or afferent nerves carry information from the periphery of the body to the brain and spinal cord. Motor nerves or efferent nerves transmit impulses from the brain and spinal cord to the periphery. Mixed nerves are composed of both motor and sensory fibers and transmit messages in both directions.
17 wrz 2016 · A fundamental activity of neurons is to modulate and effectively transmit chemical and electric signals from one neuron to another via synapses in the CNS or from one neuron to a muscle cell via junctional complexes, myoneural junctions, or motor end-plates in the PNS.
