Part One: Connective Tissues in Skeletal Muscle

Question 1

What is the name of the connective tissue surrounding a whole muscle,

shown at “1”?

Answer 1

Epimysium (dense fibrous c.t.)

Question 2

Moving upward toward the skin, tissue “1” thickens slightly and

changes names. What is it now called? What does it eventually

become just under the skin?

Answer 2

Epimysium turns into fascia, which separates adjacent muscles

(separates individual muscles from each other). As fascia extends

upward, it eventually becomes the hypodermis under the skin.

Question 3

Muscles are made up structures called fascicles. What is a fascicle?

What is the name of the connective tissue covering each fascicle,

shown at “2”?

Answer 3

Skeletal muscle is made of fascicles—which are bundles of cells.

Perimysium covers each fascicle. (areolar/loose c.t.)

Question 4

What is the name of the connective tissue that holds muscle fibers

together within a fascicle, shown at “3”?

Answer 4

Endomysium (areolar/loose c.t.)

Question 5

What type of connective tissues are these 4 structures made of?

Answer 5

See above. Fascia is dense fibrous c.t.
