Neurological Factors Affecting Movement Voluntary human movement is regulated and controlled by complex interactions within our central and peripheral nervous systems. The three major types of sensory input come from the visual (eyes), vestibular (inner ear), and somatic (body) sensory systems. The somatic sensory receptors found in muscles, tendons, ligaments, joint capsules, and skin are collectively known as proprioceptors and they gather information about body position and the direction and…

1. The peripheral nervous system, which is divided into the sensory and motor divisions, is involved in physical sensation. Sensory impulses move though the body by being stimulated by a receptor in the skin. It then travels to the sensory neurons and through the afferent fibers, were it will end up at the spinal cord as well as the brain. 2. The motor division of the nervous system are involved in skeletal muscle movement. Motor impulses move through efferent fibers. A motor unit is a motor…

My simple task was to pop a balloon. The item we used to pop the balloon was a mousetrap. I am going to go step by step through how I created my Rube Goldberg machine. First, we started out with a ramp that we dropped the ball on. That was our potential energy. Next, we had a ball drop down a tub at approximately 180°. That was mechanical energy. After that, the ball went through an elbow and hit another ball causing more mechanical energy and thermal energy from a ball hitting the other ball.…

In the first experiment, the acceleration of a falling mini-basketball, the results gathered disagreed with my predicted outcome. Originally, I could not imagine how the graph might appear. I could not visualize an object falling and what its acceleration, position, and velocity might be on the graph. However, after completing the first experiment, I realized that the graphs would look somewhat the same in relation to the basketball since this object was not affected as much as the lighter…

action potentials spontaneously and coordinating contractions during the cardiac cycle. All the cardiac muscle fibers in each region of the heart are electrically linked together. The intercalated disks are connections that electrically join the muscle fibers of the heart into a single unit that can conduct electrical impulses through the entire wall of the heart chamber without stopping. Four structures are embedded in the wall of the heart and responsible for generating the action potentials…

Bouncy balls bounce because the material of the ball is extremely elastic and can convert kinetic energy from falling into potential energy and back into kinetic energy again with little loss of momentum. They are used in many classrooms because they can easily demonstrate conservation of momentum through a highly elastic collision. Like many things made out of rubber, bouncy balls have very high elasticity, meaning they rapidly return to their resting state after being stretched or squashed. If…

Hormones operate using a type of mechanism. Releasing these hormones can trigger actions in particular target cells. One receptor on the cell membrane binds to one type of hormone. The binding hormones change the shape of the receptor, which causes the response to the hormone. Through the process of steroid hormone action, the hormone goes through a certain process of two steps. The hormone binds to receptors on the nuclear membrane once it is inside the cell that produces an…

captured by the water. Literature Review Kinetic energy is the energy of motion. The kinetic energy of an object is energy that is being used. Potential energy is stored energy that it is not in motion, but has the potential to be in motion. There are other types of potential energy like gravitational, elastic, and chemical. “Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored…

place, making action potential unlikely. Non channel synapses - neuroreceptors are enzymes that are bound to the membrane. When activated, they catalyse (cause or accelerate) the 'messenger chemical', which can have an affect on the sensitivity of the ion channel receptors in the cells. Neuromuscular junctions - synapses formed between motor neurones and muscle cells. Electrical synapses - the membranes of the two cells actually touch and they share proteins. The action potential can pass…

temperature, and circuits that allow your body to move and function. The nervous system at both a cellular and organizational level. Neurons are the primary cells of the nervous system, propagating impulses through both electric and chemical means action potentials and synaptic transmission, respectively. Neurons can be grouped together to form nerves, which are the primary organizational structures in one major branch of the nervous system, the peripheral nervous system. This is in contrast to…
