Question

multiple choice question

which describes the endomysium?

• a connective tissue sheath bundling many muscle fibers into a fascicle
• a connective tissue sheath surrounding an entire muscle
• a loose connective tissue layer around each individual muscle cell
• the plasma membrane of an individual muscle cell

Explanation:

Define the endomysium

Using the Endomysium knowledge point

• The endomysium is a thin, loose connective tissue layer (primarily reticular fibers) that surrounds each individual muscle fiber (muscle cell).

Analyze the incorrect options

Using the Perimysium and Epimysium knowledge points

• "A connective tissue sheath bundling many muscle fibers into a fascicle" describes the perimysium.
• "A connective tissue sheath surrounding an entire muscle" describes the epimysium.
• "The plasma membrane of an individual muscle cell" describes the sarcolemma.

Select the correct option

Using the Endomysium knowledge point

• The third option, "A loose connective tissue layer around each individual muscle cell," matches the definition of the endomysium.

Answer:

• (A) A connective tissue sheath bundling many muscle fibers into a fascicle
• (B) A connective tissue sheath surrounding an entire muscle
• (C) A loose connective tissue layer around each individual muscle cell (Correct answer)
• (D) The plasma membrane of an individual muscle cell
