What is the difference between extension and flexion in terms of movement in the human body?
Extension and flexion are two opposite movements in the human body. Extension refers to straightening or increasing the angle of a joint, while flexion involves bending or decreasing the angle of a joint. For example, when you straighten your arm, you are extending it, and when you bend your arm, you are flexing it.
What cranial nerve is involved in hyper extending and flexing the neck?
The spinal accessory nerve (cranial nerve XI) is involved in hyperextending and flexing the neck. This nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in these movements.
Would severing the patella tendon inactivate the hamstring group?
No, severing the patellar tendon would not directly inactivate the hamstring group. The patellar tendon is connected to the patella (kneecap) and the quadriceps muscles, not the hamstring muscles. The hamstring group is responsible for flexing the knee and extending the hip.
What is the origin and insertion of the hamstring muscles and how do they contribute to movement?
The hamstring muscles originate from the ischial tuberosity of the pelvis and insert on the tibia and fibula bones of the lower leg. They contribute to movement by flexing the knee and extending the hip joint, allowing for actions like running, jumping, and bending the knee.
Should you be able to move your kneecaps around by flexing the muscles in your thigh?
No, you should not be able to move your kneecaps around by flexing the muscles in your thigh. The kneecap is a small bone that is designed to move in a specific groove in the knee joint when the leg is bent or straightened. Trying to move the kneecap by flexing the thigh muscles can cause strain on the knee joint.
When you straighten your fingers out are you extending or flexing?
When you straighten your fingers out, you are extending them. Flexing refers to bending the joints to decrease the angle between bones, while extending refers to straightening the joints to increase the angle between the bones.
What allows you to flex and extend your lower leg and upper arms?
The muscles responsible for flexing and extending your lower leg are the quadriceps and hamstrings, while the muscles responsible for flexing and extending your upper arms are the biceps and triceps, respectively. These muscle groups work in opposition to each other to facilitate these movements.
What are Oppposing muscle in your body?
Flexors and extensors oppose each other. Think of flexing and extending your fingers as an example.
What is the difference between triceps and biceps muscles?
The triceps muscle is located on the back of the upper arm and has three heads, while the biceps muscle is located on the front of the upper arm and has two heads. The triceps muscle is responsible for extending the arm, while the biceps muscle is responsible for flexing the arm.
What is the difference between extension and flexion in terms of movement in the human body?
Extension and flexion are two opposite movements in the human body. Extension refers to straightening or increasing the angle of a joint, while flexion involves bending or decreasing the angle of a joint. For example, when you straighten your arm, you are extending it, and when you bend your arm, you are flexing it.
Is flex and extend the same?
no. flexing is deceasing the angle (e.g bending knee) extending is straightening something. (e.g. straightening knee)
What is difference between extending and flexing your arm at the elbow?
Flexion is the act of bringing two bones closer together, decreasing the angle between the two bones. Extension is the act of increasing the angle between two bones, resulting in a straightening motion.
What is the difference between tricep and bicep muscles in terms of their function and anatomy?
The tricep muscle is located on the back of the upper arm and is responsible for extending the arm, while the bicep muscle is located on the front of the upper arm and is responsible for flexing the arm. In terms of anatomy, the tricep has three heads (hence the name "tri") and the bicep has two heads (hence the name "bi").
What cranial nerve is involved in hyper extending and flexing the neck?
The spinal accessory nerve (cranial nerve XI) is involved in hyperextending and flexing the neck. This nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in these movements.
Which body system are the quadriceps part of?
The quadriceps are part of the muscular system. They are a group of muscles located at the front of the thigh and are responsible for extending the knee and flexing the hip.
What is the difference between triceps and biceps in terms of their function and anatomy?
The triceps and biceps are both muscles in the arm, but they have different functions and structures. The triceps are located on the back of the upper arm and are responsible for extending the arm, while the biceps are located on the front of the upper arm and are responsible for flexing the arm. In terms of anatomy, the triceps have three heads or sections, while the biceps have two heads.
What is the difference between muscle flexing and muscle extension?
Inn other words muscle flexing can be called muscle shortening and extension when muscle is elongating. For example when you bend you arm towards your shoulder your bicep muscle is shortening and you can feel a bump. When you extend your arm you can feel that the bump is stretching out and disappearing, that is muscle extension.
