Anatomical Position, the Person Will Access Information

¶ … anatomical position, the person will access information stored in the hippocampus regarding the object's position, height, etc. The brains motor system in areas such as the motor cortex, primary visual cortex and the motor homunculus then activate to control the motor functions via the muscle movements. Electrical impulses via neurons connected to each other via axons and dendrites travel from the brain along the spinal cord and nerve fibers to the muscles with the spinal cord which make up the central nervous system.

The impulses are then transferred to the peripheral nervous system under our control to the nerves in the hands, hips, shoulders, knees, feet, etc. To perform the step up motion. Part 2: The chemical activities in synaptic vesicles in the hippocampus activate synaptic terminals in the dendrites. The dendrites then activate neurotransmitters that impulse rapidly toward the neuron's cell body. Each nerve impulse begins in the dendrites of a neuron's. The impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.

A nerve impulse travels along the neuron in the form of electrical and chemical signals. The brain sends the message via nerve impulses involving neurons which use the neurotransmitter acetylcholine. Acetylcholine is a neurotransmitter that is released at the neuromuscular junction and triggers a muscle action potential, which leads to muscle contractions in the appropriate muscles in the hands, feet, hips, knees, etc. Every nerve impulse begins in the dendrites of a neuron's.

The impulse moves rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip. A nerve impulse travels along the neuron in the form of electrical and chemical signals. Part 3: Sliding filament theory seeks to explain muscle fiber contraction. An action potential is sent by motor neurons arriving at the neuromuscular junctions in the hip, knee, ankle and foot regions. Then this causes the muscle sarcolemma to depolarize and send more action potentials into the sarcomeres that release calcium ions from the sacroplasmic retinaculum.

This causes the actin filaments to allow the globular heads of the myosin filaments to bind to them (similar walking up a ladder) and then shorten the muscle fibers into contraction. Part 4: The joints involved in stepping up include the hip, knee, and ankle. quadriceps (thigh), hamstrings, hip flexors, gastronemius, soleus (upper and lower calf muscles) and the muscles of your lower back, abdominal and gluteous muscles. The lung and heart muscles function at their optimum to compensate the stress on these muscle groups.

The joints involved are the hip, knee, ankle joints and foot joints. Movements involved include sagittal movements such as forward and backward), lateral (right side, left side), transverse.
