Skeletal Muscle

Blank may be defined as voluntary striated muscle that is usually attached to one or more bones


Skeletal muscle exhibit a microscopic pattern of alternating light and dark bands, or blank, which result from the overlapping arrangement of the contractile proteins within each cell

Muscle Fibers

Because of their extraordinary length, skeletal muscle cells are usually called blank

Cardiac Muscle

Blank is also striated, but its involuntary- not normally under conscious control


Cardiac muscles are called blank rather than fibers

Smooth Muscle

Blank is also involuntary, and unlike skeletal and cardiac muscle, it lacks striations


Muscles enable us to move from place to place and to move individual body parts; they move body contents in the course of breathing, blood circulation, feeding and digestion, defecation, urination, and childbirth


Muscles maintain posture by preventing unwanted movements

Muscular System

Composed of the skeletal system


The study of the skeletal muscles

Fusiform Muscles

Blank are thick in the middle and tapered at each end

Parallel Muscles

Blank have a fairly uniform width and parallel fasicles

Triangular Muscles

Blank are fan-shaped- broad at one end and narrower at the other

Pennate Muscles

Blank are feather-shaped

Circular Muscles

Blank form rings around certain body openings

Indirect Attachment

the muscle ends conspicuously short of its bony destination


The gap is bridged by a fibrous band or sheet called a blank


In some cases, the tendon is a broad sheet called an blank

Direct Attachment

In a blank, there is so little separation between muscle and bone that to the naked eye, the red muscular tissue seems to emerge directly from the bone


The bony site of attachment at the relatively stationary end of a muscle is called its blank


The attachment site at the more mobile end of a muscle is called the blank


The middle, usually thicker region of a muscle is called the blank

Prime Mover

Is the muscle that produces most of the force during a particular joint action


is a muscle that aids the prime mover


The effect produced by a muscle, whether it is to produce or present a movement is called its blank


blank is a muscle that opposes the prime mover

Antagonistic Pair

The brachialis and triceps represent an blank of muscles that act on opposite sides of a joint


is a muscle that prevents a bone from moving

Intrinsic Muscle

An blank is entirely contained with a particular region, having both its origin and insertion there

Extrinsic Muscle

An blank acts upon a designated region but has its origin elsewhere


Any elongated, rigid object that rotates around a fixed point called the fulcrum


A lever is any elongated, rigid object that rotates around a fixed point called the blank


Rotation occurs when an blank applied to one point on the lever overcomes a resistance located at some other point


Rotation occurs when an effort applied to one point on the lever overcomes a blank located at some other point
