levoversion (looking left) involves:
- left lateral rectus
- right medial rectus
This is called conjugate movement (the eyes move in the same direction). Eye muscles work together with other eye muscles, of the same eye and the opposite eye, to move both eyes together in various directions. These are known as yoked eye movements.
What else can I help you with?
What extrinsic eye muscles are controlled during the convergence reflex?
The medial rectus muscles are primarily responsible for the convergence reflex. When focusing on a near object, these muscles contract to rotate both eyes inward, allowing them to converge and maintain single binocular vision.
How is a cytoskeleton like your muscles?
Both the cytoskeleton and muscles provide structure and support to cells and tissues. They are composed of protein fibers that can contract and generate force. Additionally, they both play a role in cell movement and maintaining cell shape.
What are two involuntary muscles?
Two examples of involuntary muscles are smooth muscle and cardiac muscle. Smooth muscle is found in organs such as the stomach and intestines, while cardiac muscle is found in the heart. Both types of muscles contract without conscious effort.
What are the muscles called that cross two joints and act on both joints?
Muscles that cross two joints and act on both joints are called biarticular muscles. These muscles can generate movement at both joints they cross, which can have implications for muscle function and coordination during activities involving those joints.
What are flexible and expand in the body?
Joints are flexible structures in the body that allow for movement, while muscles can expand and contract to produce movement. Together, joints and muscles work in harmony to provide flexibility and enable various types of physical activity. Stretching exercises can help improve both flexibility and muscle expansion in the body.
How do you flex?
Contract the muscles on both sides of a joint. For example, contract both your tricep and your bicep.
How is cardiac muscles similar to smooth muscles?
they both contract and relax to cause movement and both are uninucleated.
What extrinsic eye muscles are controlled during the convergence reflex?
The medial rectus muscles are primarily responsible for the convergence reflex. When focusing on a near object, these muscles contract to rotate both eyes inward, allowing them to converge and maintain single binocular vision.
What qualities do cardiac and skeletal muscles share?
Cardiac and skeletal muscles are both striated muscles that contract in response to nerve impulses. They contain sarcomeres as their basic contractile unit and rely on the presence of calcium ions for muscle contraction. Additionally, both types of muscles are composed of muscle fibers that vary in size and length.
What muscle is contracted to exhale forcibly?
Diaphragm & interna intercostal muscle
How do opposing pairs of muscles behave during movement?
When one is contracting, the opposing muscle is relaxing.
Why do we need both muscles and bones to move our body?
one muscle to contract and the other muscle to retract
What organ has involuntary and striated muscles?
The heart as both involuntary and striated muscles. The striations are similar skeletal muscles. Heart muscles are involuntary like the muscles seen in the digestive tract, called smooth muscle.
How is a cytoskeleton like your muscles?
Both the cytoskeleton and muscles provide structure and support to cells and tissues. They are composed of protein fibers that can contract and generate force. Additionally, they both play a role in cell movement and maintaining cell shape.
What specifically happens to both the bones and muscles?
Both bones and muscles are organs that are a part of a system in the body. The bones are part of the skeletal system and muscles are part of the muscular system. Both of these systems interact in order to do many complex functions, one example being that they work together to make your body move.
Which muscles contract when forearm is flexed at the elbow?
Both the tricep and the bicep are muscles which control rotational movement at the elbow. The bicep contracts when the forearm is flexed, and the tricep contracts when the forearm is extended.
What conditions need to exist in order to obligate funds on a contract that extends from on fiscal year into the next?
Both, it is for procurement of severable services and the contract does not exceed one year
