SOLUTIONS TO EXERCISES, LESSON 5
The main types of tissues in skeletal muscles are striated muscle fibers and
The large portion of skeletal muscle is known as its belly or fleshy belly.
Generally, a skeletal muscle is attached to bone by a tendon or aponeurosis. If
the fleshy portion is directly connected to the bone, it is called a fleshy attachment.
A neurovascular bundle is a branch from the main NAVL, sheathed in fibrous
connective tissue. The motor point is the specific location on the surface of the
muscle where the neurovascular bundle enters. A motor unit is a single motor
neuron and the striated muscle fibers activated by the neuron. All fibers of a motor
The trunk musculature is arranged in two ways--longitudinal muscles and oblique
muscles. The limb musculature is arranged around the joints to produce the
The components of a skeleto-muscular unit are:
The muscle which makes the main effort for a given motion is called the prime
mover (agonist). A muscle which assists the first is called a synergist. A muscle
which applies a force opposite to that of the first is called an antagonist.
