16 4 The Sensory And Motor Exams Medicine Libretexts The cranial nerves connect the head and neck directly to the brain, but the spinal cord receives sensory input and sends motor commands out to the body through the spinal nerves. whereas the brain develops into a complex series of nuclei and fiber tracts, the spinal cord remains relatively simple in its configuration (figure 16.4.1 16.4. 1 ).

The Sensory And Motor Exams But knowing the names of the nerves in order often leaves much to be desired in understanding what the nerves do. the nerves can be categorized by functions, and subtests of the cranial nerve exam can clarify these functional groupings. 16.4: the sensory and motor exams connections between the body and the cns occur through the spinal cord. Motor (also called efferent) neurons, like the one in figure 16.3.2 16.3. 2, carry nerve impulses from the central nervous system to muscles and glands. they change nerve signals into the activation of these structures. interneurons carry nerve impulses back and forth often between sensory and motor neurons within the spinal cord or brain. The target of the upper motor neuron is the dendrites of the lower motor neuron in the gray matter of the spinal cord. the axon of the lower motor neuron emerges from the spinal cord in a nerve and connects to a muscle through a neuromuscular junction to cause contraction of the target muscle. found in the skin of your fingers or toes is a type. Figure 1. the nervous system. the nervous system has three main functions: sensory input, integration of data and motor output. sensory input is when the body gathers information or data, by way of neurons, glia and synapses. the nervous system is composed of excitable nerve cells (neurons) and synapses that form between the neurons and connect.

Motor development. motor development occurs in an orderly sequence as infants move from reflexive reactions (e.g., sucking and rooting) to more advanced motor functioning. this development proceeds in a cephalocaudal (from head down) and proximodistal (from center out) direction. for instance, babies first learn to hold their heads up, then sit. A critical milestone during the sensorimotor period is the development of object permanence. object permanence is the understanding that even if something is out of sight, it still exists (bogartz, shinskey, & schilling, 2000). according to piaget, young infants do not remember an object after it has been removed from sight.
