A patient presents with a torn ligament after an athletic injury. Which tissue property best explains the slow healing process in this structure?

Appeared in: RRB Nsg. Superintendent-2026 (Shift -1st)

Explanation

Ligaments are composed of dense regular connective tissue, which consists of tightly packed, parallel collagen fibers.
This tissue type has a notoriously poor blood supply (it is avascular or poorly vascularized) compared to tissues like muscle or bone.
Tissue repair relies on blood to deliver oxygen, nutrients, and immune cells to the site of injury.
The limited vascularity of dense regular connective tissue is the primary reason for the prolonged healing time of ligament injuries.

Option B: Ligaments are made of connective tissue, not epithelial tissue. Simple squamous epithelium is a single layer of flat cells designed for rapid diffusion and filtration.
Option C: Ligaments are composed of dense regular connective tissue, not elastic cartilage. Elastic cartilage provides flexible support.
Option D: Adipose tissue is a loose connective tissue specialized for fat storage, insulation, and cushioning. It does not have the tensile strength to connect bones.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Tissue characteristics and healing properties of ligaments in the correct sequence, documenting the action clearly, and monitoring for the expected response.
Patient education is a critical nursing role. Nurses must explain to patients with ligament sprains why their recovery may be slow and emphasize the importance of adhering to treatment plans (e.g., RICE protocol, physical therapy) to prevent re-injury and promote optimal healing.
Understanding tissue healing times is crucial for discharge planning and managing patient expectations for returning to normal activities or sports.
What if the injury was a muscle strain instead of a ligament sprain? A muscle tear would typically heal much faster because muscle tissue is highly vascular, allowing for a rapid inflammatory and repair response. The treatment approach would also differ, focusing on controlled movement to align new muscle fibers.

How to Approach the Question

First, identify the key anatomical structure mentioned in the question stem: a 'torn ligament'.
Next, recall the specific type of tissue that ligaments are made of. From your anatomy and physiology knowledge, you should identify this as 'dense regular connective tissue'.
Then, analyze the clinical problem presented: 'slow healing process'.
Connect the clinical problem to the properties of the identified tissue. Ask yourself, 'What characteristic of dense regular connective tissue would cause slow healing?' The answer is its poor blood supply (avascularity).
Finally, evaluate the given options. Select the option that correctly links the tissue type (dense regular connective tissue) with the property that explains the clinical problem (limited blood supply).
