Which of the following correctly differentiates ligament from tendon in human connective tissue?
Ligament connects bone to bone; tendon connects muscle to bone
Tendon is elastic, while ligament is completely non-elastic
Ligament connects muscle to bone, while tendon connects bone to bone
Both ligament and tendon connect bones to bones but differ in color
Ligament connects bone to bone; tendon connects muscle to bone
Ligaments are tough, fibrous connective tissues that join bone to bone to stabilize joints, whereas tendons are dense connective tissues that attach muscles to bones to facilitate movement. While both are composed primarily of collagen, they differ in fiber arrangement and functional elasticity.
Ligaments are tough, fibrous connective tissues that join bone to bone to stabilize joints, whereas tendons are dense connective tissues that attach muscles to bones to facilitate movement. While both are composed primarily of collagen, they differ in fiber arrangement and functional elasticity.
Think of a ligament as a 'hinge stabilizer' that keeps door frames aligned, while a tendon acts as a 'pulley rope' that pulls the door to swing it open.
B-L-B (Bone-Ligament-Bone) and M-T-B (Muscle-Tendon-Bone).
╧Г=AFтАЛ тАФ representing stress (force per unit area) which tendons are structurally optimized to withstand during muscle contraction.
Tendons consist of highly organized, parallel collagen fibers to withstand high unidirectional tension during muscle contraction. Ligaments contain more elastin fibers mixed with collagen, allowing for slight, controlled stretching to maintain joint integrity and prevent dislocation under mechanical stress.
Ligaments provide passive stability to joints.
Tendons act as shock absorbers and transmit force from muscles to bones.
Both tissues are classified as Dense Regular Connective Tissue.
Ligaments limit joint range of motion to prevent injury.
Tendons efficiently transfer mechanical energy from muscle fibers to the skeletal system.
Both tissues have poor vascularity, leading to slow healing rates after injury.
Excessive tension causes micro-tears (sprains for ligaments, strains for tendons).
Anterior Cruciate Ligament (ACL) reconstruction in knees.
Achilles tendon repair following sports injuries.
| Feature | Ligament | Tendon |
|---|---|---|
Function | Connects Bone to Bone | Connects Muscle to Bone |
Elasticity | Higher (contains elastin) | Lower (mainly collagen) |
Collagen Type I is the predominant protein in both.
Option B is incorrect because both tissues possess some level of elasticity; ligaments are actually more elastic than tendons.
Option C is incorrect as it reverses the functional roles of both tissues.
A is correct тАФ Ligaments anchor bones to bones, while tendons bridge the gap between muscles and bones.
Always remember the suffix 'Ligament' relates to linking (binding) bones, while 'Tendon' is related to 'Tension' created by muscle contraction.
