Which describes muscle insertion?

Muscle insertion refers to a muscle’s distal attachment—the end of the muscle furthest away from the torso. For example, the bicep insertion occurs at the elbow.

Which of the following describes muscle insertion quizlet?

The insertion is the attachment of a muscle to the bone or structure that moves when the muscle contracts.

Which of the following describes the origin of a muscle?

Muscle origin refers to a muscle’s proximal attachment—the end of the muscle closest to the torso. For example, the bicep muscle’s origin is located at the shoulder.

How does muscle attach to muscle quizlet?

Tendon: At the end of each muscle, collagen fibers of the epimysium, perimysium, and endomysium converge to form a tendon which attaches the muscle to a bone, skin, or another muscle. … Each muscle fiber has one neuromuscular synapse located in middle.

Which of the following muscles has its insertion on the sternum?

Sternalis muscle
Origin manubrium of sternum or clavicle
Insertion xiphoid process, pectoral fascia, lower ribs, costal cartilages or rectus sheath
Latin Musculus sternalis

Which of the following terms describes a muscle that assists the muscle that is primarily responsible for a given action?

The muscle primarily responsible for a movement is called the prime mover, and muscles that assist in this action are called synergists. A synergist that makes the insertion site more stable is called a fixator. Meanwhile, a muscle with the opposite action of the prime mover is called an antagonist.

How do muscle attach to muscle?

Tendons are cords made of tough tissue, and they work as special connector pieces between bone and muscle. The tendons are attached so well that when you contract one of your muscles, the tendon and bone move along with it. Skeletal muscles come in many different sizes and shapes to allow them to do many types of jobs.

What kind of signals are used in your body to tell muscles to contract quizlet?

When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the muscle.

Which type of muscle makes up the muscles of the body quizlet?

Skeletal Muscle Skeletal muscle, also called voluntary muscle, is the only type of muscle that you can control. Skeletal muscles are attached to bones and are responsible for moving the body.

Where do muscles attach?

A tendon is a fibrous connective tissue that attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.

How do muscles learn origin and insertion?

What is insertion anatomy?

The insertion of a muscle is defined as the place where one end of a muscle is attached to the freely moving bone of its joint.

What kind of tissue connects muscle to muscle?

tendon, tissue that attaches a muscle to other body parts, usually bones. Tendons are the connective tissues that transmit the mechanical force of muscle contraction to the bones; the tendon is firmly connected to muscle fibres at one end and to components of the bone at its other end.

What muscles are voluntary?

Which muscles are voluntary? Voluntary muscles are skeletal muscles that attach to bones and can be consciously activated to control movement. Common voluntary skeletal muscles include the biceps, triceps, lats, abdominals, glutes, quadriceps, and hamstrings.

Which type of muscle is attached to the bones and helps produce body movement?

Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Together, skeletal muscles and bones are called the musculoskeletal system (also known as the locomotor system).

How do muscles attach to tendons?

Connective tissues that transmit the force generated by muscle contraction to the skeleton. The tendons integrate with the muscle and skeletal tissues through specialized structures termed the myotendinous junction and the enthesis, respectively, that provide flexible but robust and resilient anchor points.

How does muscle attach to bone?

Skeletal muscle is attached by cord-like tendons to bone, such as in the legs, arms, and face. Skeletal muscles are called striated (pronounced: STRY-ay-ted) because they are made up of fibers that have horizontal stripes when viewed under a microscope.

What type of tissue is muscle?

skeletal muscle tissue
Muscle tissue can be categorized into skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue. Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations.

How do ligaments attach to bone?

At fibrous entheses, the tendon or ligament attaches either directly to the bone or indirectly to it via the periosteum. In both cases, dense fibrous connective tissue connects the tendon/ligament to the periosteum and there is no evidence of (fibro)cartilage differentiation (Fig.

Which structure is the site of attachment for tendons?

Entheses (insertion sites, osteotendinous junctions, osteoligamentous junctions) are sites of stress concentration at the region where tendons and ligaments attach to bone.

Which structure is the site of attachment for tendons quizlet?

The epiphyseal plate is involved in bone growth. a membrane that surrounds the surface of a bone. is involved in bone growth, repair and development. It also serves as a site of attachment for ligaments and tendons.
