Spinal Cord Reflexes

Dorsal and ventral roots join to form a mixed nerve that carries both afferent and efferent nerves Spinal Nerve
functional groups of neuron (interneurons), limited input and output destinations, may stimulate/depress part of the brain and spinal cord Neuronal Pool
Spreads stimulation to many neurons/neuronal pools in CNS (Vision---conscious I see, unconscious posture and balance) Divergence
Brings many input sources into a single neuron (Breathing) Convergence
Moves information in a single line (pain) Serial Processing
moves info along several paths simultaneously (pain, withdraw, cuss) Parallel Processing
automatic responses coordinated within the spinal cord, through sensory, motor and interneurons Reflex
sensory neurons synapse directly on motor neurons, rare (stretch reflex)Complexity of circuit Monosynaptic Reflex Arc
at least one interneuron is between sensory and motor neuron, (tendon reflex, withdraw reflex)Complexity of Circuit Polysynaptic Reflex Arc
genetically determined Developemental Reflex Innate Reflexes
Learned Developemental Reflex Acquired Reflexes
Control Skeletal Muscle contractions, Includes superficial and stretch reflexes Response Reflex Somatic reflexes
Controls actions of smooth muscle, glands,cardiac muscle and adipose tissue, Response Reflex Visceral (Autonomic) Reflexes
Processed in the Spine Spinal Reflexes
Processed in the brain Crainial Reflexes
Occur on the same side of the body as the stimulus, stretch, tendon, withdraw reflex Ipsilateral Reflex arcs
Occur on the opposite side of the stimulus, occur simultaneously with flexor reflex by reverberating circuits until consciously overridden Contralateral Reflex arcs
monosynaptic reflex in which muscle spindles are the receptors, that have the least delay in sensory and motor output (patellar reflex) Stretch Reflex
bags of fibers, innervated by sensory/motor neurons Intrafusal Fibers
Maintain tone, contract muscle Extrafusal Fibers
