How do joint movement increase?
Joint movement increases through the action of muscles pulling on the bones that form the joint. When muscles contract and exert force, the bones are brought closer together, allowing for movement at the joint. Additionally, the structure and integrity of the joints, ligaments, tendons, and cartilage play a role in facilitating smooth and coordinated movement.
What is the function of the chordae tendineae and the papillary muscles?
The chordae tendinae bring the right ventricular walls closer together, pull semilunar and AV valves open and prevent ballooning of AV valves. The papillary muscles help in the closure and opening of mitral and tricuspid valves.
Bending the knee joint to bring the lower-leg and upper-leg bones closer together?
This movement is called knee flexion. It is controlled by the hamstrings at the back of the thigh and the calf muscles. The knee joint flexes to allow the leg to bend and bring the lower leg towards the upper leg.
What is the functional unit of a muscle and how does it contribute to muscle contraction?
The functional unit of a muscle is called a sarcomere. Sarcomeres are made up of overlapping filaments of actin and myosin proteins. During muscle contraction, the myosin filaments pull the actin filaments closer together, causing the muscle to shorten and generate force. This process is repeated throughout the muscle, allowing it to contract and produce movement.
How does a human bend an arm?
Bending an elbow is similar to bending a knee. First, your brain sends impulses through your central nervous system and throughout your nerves. Then, the impulses cause flexible muscles to contract and relax, making them lengthen and shrink. Your muscles are connected to your bones by tendons, a connective tissue. As muscles contract and relax, they pull and push on the tendons to pull and push on the bones, allowing a joint to bend. Your biceps contract and triceps relax to bend your elbow. Your biceps relax and tripceps contract to straighten your elbow.
What are deep muscles called?
The deep muscles of the human body are generally called intrinsic muscles. The muscles that are closer to the skin are called superficial muscles.

What are Muscle that brings bones together?
Muscles that bring bones together are primarily known as adductor muscles. These muscles function to pull limbs or other body parts closer to the midline of the body. For example, the adductor muscles of the thigh help bring the legs together. Additionally, the muscles around joints, such as the pectorals and latissimus dorsi in the upper body, can also assist in this action by stabilizing and moving bones closer together.
How wouid you move your body if there were no skeleton?
You wouldn't be able to, how muscles work is when they contract they pull two or more bones closer together to preform movement so without bones there would be no way for your body to move.
How is movement possible?
The cerebellum is the movement center of the brain which will send signals along the neuro-pathway to skeletal muscles and will contract by shortening their length and being thicker to pull two or more ligaments which are connect to bones closer together.
What are the muscles called that bring a body part toward the body?
The muscles that bring a body part toward the body are called adductor muscles. They are responsible for moving a part of the body closer to the midline.
When water molecules are moving closer together in the air is called?
When water molecules are moving closer together in the air, it is called condensation. This process occurs when the water vapor in the air loses heat, causing the molecules to slow down and come together to form liquid water droplets.
How do joint movement increase?

When muscles contract and exert force, the bones are brought closer together, allowing for movement at the joint. Additionally, the structure and integrity of the joints, ligaments, tendons, and cartilage play a role in facilitating smooth and coordinated movement.
What is the muscle that closes a joint?
Muscles that brings the two (or more) bones that form it closer are called flexors.
When grains move closer together it is called?
When grains move closer together, it is called compaction. This process involves reducing the pore space between grains, leading to a denser arrangement of particles.
