In the context of muscle attachments (origin and insertion), what structure connects a skeletal muscle to a bone?
A
Tendon
B
Articular cartilage
C
Fascia
D
Ligament
Verified step by step guidance1
Step 1: Understand the definitions of the key terms related to muscle attachments. The origin is the fixed attachment point of a muscle, while the insertion is the movable attachment point.
Step 2: Identify the structure that connects muscle to bone. This structure must be able to transmit the force generated by the muscle contraction to the bone to produce movement.
Step 3: Review the options: Tendon, Articular cartilage, Fascia, and Ligament. Consider the function of each: Tendons connect muscle to bone; ligaments connect bone to bone; fascia is connective tissue surrounding muscles; articular cartilage covers bone surfaces in joints.
Step 4: Conclude that the structure connecting skeletal muscle to bone, facilitating movement, is the tendon.
Step 5: Remember that tendons are composed of dense connective tissue, which provides strength and flexibility necessary for muscle-bone attachment.
