this would allow a faster healing time for both the limb and the victim with minimal scarring for the tissue and skin. 4. Shortening of a bone: Shortening of the bone will simplify the repair of the nerves and blood vessels which makes it possible for the single suture of an artery‚ vein‚ and/or nerve as necessary. It also allows for the soft tissue on either side of the bone easier to put together. 5. Movements associated with arm‚ forearm‚ wrist‚ and fingers: a. Shoulder: flexion‚ extension

P5 – Physical and psychological theories of ageing Physical changes Hormones and Menopause: When it comes to hormones and menopause Alicia may have had a decrease in the hormone oestrogen which is known to be connected with the osteoporosis. This would have caused Alicia to be at some kind of risk of osteoporosis than others if she had genetically inherited it. However‚ to prevent osteoporosis Alicia could had exercise sessions or any different type of fitness which would have helped her strengthen

Sketch the skeletal muscle cross section. Identify the muscle fibers‚ endomysium and perimysium. Describe what you observed on the slide. Questions A. Why do muscle fibers need to be wrapped and bundled into groups? So that nerves can send a signal to the bundle instead of each individual fiber. Extensions and Flexions are also much more capable because of bundles. B. Which tissue comprises the muscle wrappings? Why?

The 2000-Meter Row: A Case in Homeostasis Adapted from the National Center for Case Study Teaching in Science* by Nathan Strong At the start 1. Recall that Jim’s heart and respiratory rate are increased‚ he was sweating and that his mouth was dry before the raise began. Explain what is happening to his autonomic nervous system (including which division is the most active) and specify exactly how those ANS responses are creating the symptoms noted. What changes do you think are occurring

Through this‚ we can delve deeper by understanding how nerves‚ through the actions Of various neurotransmitters affect the motility of the gastrointesital tract. Furthermore‚ we can investigate The effects of drugs‚ and their uses in replicating effects of autonomic neurotransmitters as well as The way certain drugs can interfere with autonomic neurotransmitters and how they interact with Their target tissues. A. RESPONSES TO NERVE STIMULATION Attach a copy of your experimental recordings

No summation 9. Why is it important that summation not occur in heart muscle? Summation would increase the Heart muscle contractions which would lead to heart attack. Activity 2: Vagus Nerve Stimulation 1. Describe the effect of the vagus nerve stimulation on the heartbeat. The vagus nerve stimulation caused the heartbeat to flatline and then restart and react normally 2. Soon after you applied the stimuli‚ did the heart rate increase or decrease? Soon after the stimulation is

The Muscular System: Contraction of Motor Units 1. Define a motor neuron:_____A single nerve cell that branches from the brain or the spinal cord to a muscle or a gland. 2. Define a motor unit: ___A motor neuron and all of the muscle fibers it stimulates. 3. The synapse between a motor neuron and the muscle it innervates is called a ____neuromuscular junction_______. 4. The stimulation of additional motor units will increase the strength of the contraction. This process is called

This is a collection of disorders that occurs when nerves of the peripheral nervous system are damaged. This is located near the nervous system outside of the brain and spinal cord. Neuropathy causes many things such as pain and numbness in the hands and feet. But this results from traumatic injuries‚ infections‚ metabolic disorders‚ and exposure to toxic. Diabetes is the most common causes of neuropathy. Having this disorder can affect nerves that control the muscle movement; it can also affect

Neurons: The Basic Elements of Behavior Neurons‚ or otherwise called nerve cells‚ are the basic elements of our nervous systems. We have as many as one trillion nerve cells throughout our bodies. These cells are responsible for controlling our behavior. So what is a neuron? “A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways‚ but there is one key difference between neurons and other cells
