NROC64H3 Lecture Notes - Lecture 6: Lower Motor Neuron, Alpha Motor Neuron, Upper Motor Neuron
Document Summary
Saq: tell me about the somatosensory afferent axons, aa, ab, ad, c, which ones exist, how are they different morphologically. In terms of transmission: from aa c, aa is fastest, c is slowest. Motor programs: motor system, muscles and neurons that control muscles, role, generation of coordinated movements, parts of motor control, spinal cord coordinated muscle contraction, brain motor programs in spinal cord. The somatic motor system: types of muscles, smooth, digestive tract, arteries, striated, cardiac, skeltal, somatic musculature, axial muscles, trunk movement, proximal muscles, shoulder, elbow, pelvis, knee, distal muscles, hands, feet, digits, lower motor neuron. Information from joint receptors: combined with, muscle spindle, golgi tendon organ, skin receptors, spinal interneurons, synaptic inputs, primary sensory axon, descending axons from brain, collaterals of lower motor neuron axons. Concluding remarks: spinal control of movement, different level of analysis, sensation and movement linked, direct feedback.
