Fascia is:

• a band or sheet of connective tissue that supports and surrounds muscles and other organs

• a type of bone tissue found in the body

• a gland that produces hormones

• a layer of skin protecting the body

Epimysium and perimysium are:

• connective tissue layers surrounding muscles

• types of muscle fibers

• enzymes involved in muscle contraction

• hormones regulating muscle growth

Fascicles are:

• Bundles of muscle fibers

• Types of connective tissue

• Individual muscle cells

• Nerve endings in muscles

The endomysium is:

• a connective tissue that surrounds individual muscle fibers

• a type of muscle protein

• the outermost layer of muscle tissue

• a nerve that supplies muscles

The sarcolemma and sarcoplasm are:

• the cell membrane and cytoplasm of a muscle fiber, respectively.

• types of connective tissue in muscles.

• enzymes involved in muscle contraction.

• parts of the nervous system controlling muscles.

Myofibrils are:

• the basic rod-like units of a muscle cell

• a type of connective tissue

• the outer membrane of a muscle fiber
