ANATOMY 1 Lecture Notes - Lecture 13: Symphysis, Intervertebral Foramina, Muscle Contraction
Document Summary
Back of knee-popliteal; oblique & arcuate lateral-fibula. H zone-only when muscle is relaxed; thick only. *which structure is present in middle of sarcomere thin filaments. Myosin, golf clubs troponin tropomyosin thick filaments. Cns: central nervous system; brain, spinal cord. Pns: peripheral nervous system; cranial and spinal nerves. 31 pairs spinal nerves, exit through intervertebral foramina. Sensory neurons running from stimulus receptors that inform the cns of the. Motor neurons running from the cns to the muscles and glands - called stimuli effectors - that take action. Proprioception: ability to sense stimuli arising within the body regarding position, motion, and equilibrium. Ventral: pericardial, pleural, peritoneal: monitor stimuli, integration, motor output. Synapse: junction between two nerve cells, consists gap across which impulses pass by diffusion of a neurotransmitter. Dendrites: short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body.
