Ron stumbled on a nail while looking for his shoes. The pain made him step back and fall. Which muscle tissue or tissues contributed to Ron's response?
Skeletal muscle tissue contributed to Ron's response. Skeletal muscles are responsible for voluntary movement and are connected to bones via tendons. They're also to blame for your body's automatic reactions, like the ones you probably felt when Ron stepped on a nail.
If you want to increase your range of motion, what should you do first?
Start slowly, performing each exercise only a few times at first, and gradually increase the frequency. By moving just enough to feel a slight stretch, but without forcing it, try to achieve full range of motion. Only go as far as the point of resistance. Avoid pushing yourself too hard.
Repeating units are present in each myofibril of the muscle cell and run end to end along the myofibril's length. What is the name for these units?
Sarcomeres are the repeating units of myofibrils. The contraction of the muscles is caused by these sarcomeres.
If you want to increase your range of motion, what should you do first?
Transverse tubule is the name of the structure that transports the excitatory neuronal impulse from the sarcolemma to the sarcoplasmic reticulum. Action potentials can conduct quickly through the sarcolemma thanks to a deep invagination that runs parallel to the myofibrils.
In order to move large objects, a machine with a lever system is built. Which of these would be the best for carrying a big weight with minimum exertion of effort or force?
When the mechanical advantage of a lever is great, it may move a lot of weight with a small amount of force. Mechanical advantage is always high for second-class levers. High mechanical advantage may be achieved with first-class levers if the fulcrum is situated in close proximity to the load.
Please pick the best way to explain proprioception.
Your body's capacity to perceive movement, action, and location is known as proprioception, also referred to as kinesthesia. It can be found in every muscle movement you make. You couldn't move without thinking about your next step if proprioception didn't exist.
Physical therapists typically use which of the following tools to measure joint angle?
In physical therapy, joint angles are measured with instruments called goniometers. Useful for diagnosing the extent of joint injuries and determining appropriate treatment.
