To provide attachment points for muscles
Which of the following statements about tendon injuries is true?
Tendon injuries are often slow to heal due to their poor vascularization

To connect muscle to bone and transmit force from the muscle to the bone.
Which of the following is a characteristic of tendons?
They have a brilliant white color and great resistance to mechanical loads.
What is the primary function of an aponeurosis?
To provide a wide attachment for muscles to bone or other muscles.
Why are damaged tendons slow to heal?
Tendons are poorly vascularized and have low metabolic needs, making them slow to heal.
What is the primary function of the linea alba?
To act as a seam or line of union between the aponeuroses of the abdominal wall muscles.
What is the function of a tendon bursa?
To reduce friction and allow smooth gliding of the tendon over bony prominences.
How do tendons differ from aponeurosis?
Tendons transmit force from muscle to bone, while aponeurosis provides a wide attachment for muscles.
What type of injury can occur when excessive tension is applied to a tendon?
Avulsion fracture, where the tendon attachment pulls a piece of bone away.

Avulsion fracture
Which of the following is an intrinsic factor that can contribute to tendinopathies?
Nutrition
What is the primary function of the tendon of insertion (distal attachment)?
To move the muscle during contraction
Which of the following statements about tendons is true?
Tendons are slow to heal when damaged
What is the primary function of the tendon of origin (proximal attachment)?

Which protective structure surrounds a tendon when it is vulnerable along a greater part of its circumference?
Tendon sheath
What type of injury can occur when excessive tension is applied to a tendon?
Avulsion fracture
Which of the following is an intrinsic factor that can contribute to tendinopathies (tendon injuries)?
Age
What is the function of a tendon bursa?
To allow the tendon to glide over bony prominences
Which structure is present when the deep digital flexor tendon glides over the distal sesamoid bone?
Fibrocartilagenous segment
Which of the following is an extrinsic factor that can contribute to tendinopathies (tendon injuries)?
Excessive forces or loading
What does the image of the old avulsion fracture of the calcaneus in a 6-year-old mare illustrate?
A tendon injury caused by excessive tension
What is the primary function of a tendon?
To transmit the force of muscle contraction to the bone
What is the main difference between a tendon and an aponeurosis?
Tendons are cord-like structures, while aponeuroses are sheet-like
Which of the following is a protective structure that surrounds a tendon when it is vulnerable along a greater part of its circumference?
Tendon sheath
Why are damaged tendons slow to heal?
Tendons are poorly vascularized and have low metabolic needs
What is the primary function of the linea alba?
To act as a seam where the aponeuroses of the abdominal wall muscles meet
What is the primary function of a tendon bursa?
To absorb shock and reduce friction between the tendon and bone
