What 12 structures receive and send sensory and motor signals between the body and brain
Cranial nerves. Twelve pairs of cranial nerves exit the ventral surface of the brain.
Sensory nerves are part of the peripheral nervous system. This is also called the PNS for short. Sensory nerves work in conjuction with the senses, to receive and transmit signals and impulses from the sensory organs.
Dendrite
The medical term for root-like structures of a nerve that receive impulses and conduct them to the cell body is "dendrites." Dendrites are specialized extensions of nerve cells that branch out to receive signals from other neurons and transmit these signals to the cell body for processing.
A spinal nerve which carries motor, sensory, and autonomic signals between the spinal cord and the body.
Sensory receptors translate physical energy into neural signals.
The sensory neural pathways set the brain's ability to interpret signals that control intellectual, emotional, psychological and physical responses to stimuli. The sensory systems ie. vision, hearing, touch, taste, smell and proprioceptor motion bring sensory signals to the brain and then interpret those signals. During development there is a critical period for sensory neural circuits. To form what is known as synapses (the connection between neurons that helps to carry these signals from neuron to neuron ), stimuli is needed. When this stimulation is not available in the critical period and deficits occur in the region of the cortex responsible, it can not be corrected at a later stage.
sensory nerves
No, a dendrite is not bordered by a synapse. A synapse is a junction between two neurons where communication occurs by the release of neurotransmitters. Dendrites are the branching structures of a neuron that receive signals from other neurons through these synapses.
Sensory receptors send signals to sensory neurons.
Sensory neuron is to motor neuron...as feedback system is to control system. The motor neurons send signals from the brain to control the body. The sensory neurons send signals from the body back to the brain.
most nerves carry 2 types of fibre 'sensory 'or 'afferent 'fibres bring messages from receptors in the sense organs and other structures to the spinal cord and brain. 'motor'or 'efferent' fibres convey signals from the brain or spinal cord to a muscle or gland. some nerves contain just sensory fibres e.g.optic nerve whilst others have just motor fibres.
