beginning of muscle tissues

Skeletal Muscle Tissue

The type of muscle tissue that is attached to bones and under voluntary control.

Smooth Muscle Tissue

The type of muscle tissue found in the walls of hollow internal organs, under involuntary control.

Cardiac Muscle Tissue

The muscle tissue found in the heart that is involuntary and has striations.

Agonist

The muscle that is the prime mover for a specific action.

Antagonist

The muscle that opposes the action of the agonist.

Synergist

A muscle that assists the prime mover in performing a specific action.

Origin of a Muscle

The point of attachment that does not move when a muscle contracts.

Insertion of a Muscle

The point of attachment that moves when a muscle contracts.

Fascia

The dense connective tissue that wraps around the entire muscle.

Tendon

A cord-like structure that connects a muscle to a bone.

Aponeurosis

A sheet-like structure that anchors a muscle to an origin or insertion.

Myofibril

The contractile subunit within a muscle fiber that contains myofilaments.

Sarcoplasm

The cytoplasm of a muscle fiber.

Sacrolemma

The plasma membrane of a muscle fiber.

Intercalated Discs

Specialized connections between cardiac muscle fibers.

Striations

The stripes evident on skeletal and cardiac muscle fibers due to the arrangement of myofilaments.

What is skeletal muscle tissue?

Skeletal muscle tissue is the type of muscle tissue that is attached to bones and is under voluntary control.

Where is smooth muscle tissue found?

Smooth muscle tissue is found in the walls of hollow internal organs and is under involuntary control.

What is the function of cardiac muscle tissue?

Cardiac muscle tissue is found in the heart, involuntary, and has striations.

What is an agonist in muscle movement?

The agonist is the muscle that acts as the prime mover for a specific action.

What role does the antagonist muscle play?

The antagonist muscle opposes the action of the agonist.

What is a synergist?

A synergist is a muscle that assists the prime mover in performing a specific action.

What is the origin of a muscle?

The origin is the point of attachment that does not move when a muscle contracts.

What does insertion refer to in muscle anatomy?

Insertion is the point of attachment that moves when a muscle contracts.

What is fascia?

Fascia is the dense connective tissue that wraps around the entire muscle.

What connects a muscle to a bone?

A tendon is the cord-like structure that connects a muscle to a bone.
