The main difference between muscle and tendon is that the muscle is a bundle of fibrous tissue made up of muscle cells while the tendon is an inelastic cord made up of connective tissue.
Muscle and tendon are two anatomical structures of the body, which support the body while aiding movement. Also, the main function of a muscle is to assist in movement by contracting while the tendon attaches the muscles to the bones.

Muscle is a fibrous tissue made up of muscle cells. The three types of muscles in the body are smooth muscles, skeletal muscles, and heart muscles.
A tendon is a tough cord that connects muscles to bones. It is made up of dense, white fibrous connective tissue. This connective tissue contains mainly collagen fibers. The basic unit of a tendon is the primary collagen fiber. A group of primary collagen fibers constitutes the primary fiber bundle called the subfasciculus.
A group of subfascicles forms the secondary fiber bundle called a fascicle. Several fascicles form a bundle of tertiary fibers called the tendon unit. A layer of connective tissue called the endotenon covers each bundle of primary, secondary, and tertiary fibers. The epitenon is the connective tissue layer that covers the tertiary fiber bundle.
Furthermore, there are two types of cells in the tendon: tenocytes, the mature cells that originate from fibrocytes, and tenoblasts, the immature cells that originate from fibroblasts. Tenocytes attach to collagen fibers, while tenoblasts occur in groups, which secrete collagen and the extracellular matrix of connective tissue.
The main function of a tendon is to transmit the forces exerted by the muscles to the bones. Therefore, tendons occur at each end of a muscle. Due to the high tensile strength of a tendon, it can withstand the great pressure generated by the muscle.
1: Muscle refers to a band or bundle of fibrous tissue in a human or animal body that has the ability to contract, produce movement or maintain the position of body parts. A tendon refers to a flexible but inelastic cord of strong fibrous collagen tissue that attaches a muscle to a bone. Thus, this explains the basic difference between muscle and tendon.

4:The main function of the muscles is to aid in movement by contracting, while that of the tendons is to connect the muscles to the bones. Hence, this is another important difference between muscle and tendon.
