CTBS Anatomy and Physiology 2

Question 1

Which type of cartilage is found in the intervertebral discs and serves as a shock absorber in the spine?

Accepted Answer

Fibrocartilage

Answer

Fibrocartilage, found in intervertebral discs, provides tensile strength and compressive resistance for spinal shock absorption.

Question 2

The periosteum serves which critical function relevant to bone tissue banking?

Accepted Answer

Providing a vascular supply and osteoprogenitor cells for bone repair

Answer

The periosteum contains osteoprogenitor cells and blood vessels that are essential for bone regeneration and healing.

Question 3

In the context of tissue donation, which layer of the cornea provides the majority of its structural tensile strength?

Accepted Answer

Stroma

Answer

The corneal stroma, composed of organized collagen lamellae, accounts for approximately 90% of corneal thickness and its tensile strength.

Question 4

Which anatomical structure separates the cortical bone from the medullary cavity and is relevant when processing femoral shaft allografts?

Accepted Answer

Endosteum

Answer

The endosteum is a thin connective tissue lining the inner surface of cortical bone, bordering the medullary cavity.

Question 5

A tissue bank is processing patellar tendon grafts. The patellar tendon is primarily composed of which collagen type?

Accepted Answer

Type I collagen

Answer

Tendons, including the patellar tendon, are predominantly composed of type I collagen arranged in parallel bundles for tensile strength.
