What is an ligament?
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.
Where are tendons derived from?
mesenchyme
The tendons and ligaments are derived from the mesenchyme that is resident in the early limb bud and the earliest known marker for tendon formation is scleraxis (Scx) (Cserjesi et al., 1995).
Where do you get Aponeurosis?
Aponeuroses are connective tissues found on the surface of pennate muscles and are in close association with muscle fascicles. In addition to transmitting muscle forces to the external tendon, aponeurosis has been hypothesized to influence the direction of muscle shape change during a contraction.
What is an example of a ligament?
Ligaments appear as crisscross bands that attach bone to bone and help stabilize joints. For example, the anterior cruciate ligament (ACL) attaches the thighbone to the shinbone, stabilizing the knee joint. Tendons, located at each end of a muscle, attach muscle to bone.

What surrounds a tendon?
The tendons are surrounded by loose, porous connective tissue, which is called paratenon. A complex structure, paratenon, protects the tendon and allows shifting tendon cover format. Tendon sheaths consist of two continuous layers: parietal on the outside and visceral on the inside.
Where is a tendon?
Tendons, located at each end of a muscle, attach muscle to bone. Tendons are found throughout the body, from the head and neck all the way down to the feet. The Achilles tendon is the largest tendon in the body. It attaches the calf muscle to the heel bone.
Why is aponeurosis so important?
An aponeurosis is a type of connective tissue found throughout the body. Aponeuroses provide an attachment point for muscles to connect to bone, and can also envelope muscles and organs, bind muscles together, and bind muscles to other tissues. They are important for muscle movement and posture.
What does an aponeurosis do?
Their primary function is to join muscles and the body parts they act upon, whether bone or other muscles. They have a shiny, whitish-silvery color, are histologically similar to tendons, and are very sparingly supplied with blood vessels and nerves. When dissected, aponeuroses are papery and peel off by sections.
What is the difference between the endotenon and epitenon?
The endotenon and epitenon, which surrounds the type I collagen, primarily consists of type III collagen. Structurally, tendons are made up of fascicles surrounded by epitenon. The fascicles are a collection of collagen fibrils surrounded by an endotenon.
Where does the word epitheton come from?
[Latin epitheton, from Greek, neuter of epithetos, added, attributed, from epitithenai, epithe-, to add to : epi-, epi- + tithenai, to place; see dhē- in Indo-European roots .] American Heritage® Dictionary of the English Language, Fifth Edition.

What is the function of the paratenon and epitenon?
The paratenon and the epitenon form together the peritenon. Later work demonstrated the capacity of tendons to heal intrinsically [7]–[10], and it is now believed that both intrinsic and extrinsic healing play a synergistic role in tendon regeneration [11], [12]. However, the extent of the contribution of each is still not well defined.
What is an epithet?
a descriptive word or phrase added to or substituted for a person’s name: “Lackland” is an epithet for King John. n. 1. a characterizing word or phrase added to or used in place of the name of a person or thing. 2. a word, phrase, or expression used invectively as a term of abuse or contempt.
