Insertion
Attachment to movable bone
Complete & color-code
(#14)

8. Types of Muscles Complete #16
Prime mover—muscle with major responsibility for a certain movement
Antagonist—muscle that opposes or reverses a prime mover
Synergist—muscle that aids a prime mover in a movement & helps prevent rotation
Fixator—stabilizes origin of a prime mover
Complete #16

9. Naming Skeletal Muscles
By direction of muscle fibers
Examples
Rectus (straight)
Transverse (horizontal)
Oblique (angle)
By relative size of the muscle
Maximus (largest)
Minimus (smallest)
Longus (longest)
By location of the muscle
Examples
Temporalis (temporal bone)
Occipitalis (occipital bone)
By number of origins
Triceps (3 heads)
Biceps (2 heads)
Quadriceps (4 muscles in group)

10. Naming Skeletal Muscles
By location of the muscle’s origin & insertion
Example
Sternocleidomastoid (on the sternum)
By action of the muscle
Examples
Flexor (flexes a bone)
Extensor (extends a bone)
Abductor (abducts a limb)
Adductor (adducts a limb)
By shape of the muscle
Deltoid (triangular)
Trapezius (trapezoid)

11. Superficial Muscles: Anterior
Identify (by number) & color-code (all the same color) the following Anterior Muscles:
-Orbicularis oris
-Pectoralis major
-External oblique
-Adductor group
-Vastus medialis
Muscle Quiz #1

12. Superficial Muscles: Posterior
Identify (by number) & color-code (all the same color) the following Posterior Muscles:

13. Naming Skeletal Muscles Review
Identify 1 skeletal muscle we have learned that is named for…
Its relative size?
Gluteus maximus
Its location on the body?
Latissimus dorsi
Its shape?
Orbicularis oris
The number of origins?
Biceps brachii
The direction of muscle fibers?
External obliques

14. Have out your Muscle Tissue Comparison checklist…
How many different types of muscle
tissue is found in the body? 3!

15. The Muscular System
Muscles are responsible for all types of body movement
3 muscle types are found in the body
Skeletal muscle
Attached to bone & skin
Produce movement, stabilize joints, provide posture & generate heat
Cardiac muscle
Walls of the heart
Protect the heart & produce contractions of the heart walls
Smooth muscle
Walls of hollow visceral (i.e, stomach) organs (except heart)
Protect organs & produce slow contractions

16. Comparison of Skeletal, Cardiac & Smooth Muscles

17. Characteristics of Muscles
All muscles share some terminology
myo & mys refer to “muscle”
sarco refers to “flesh”
Skeletal & smooth muscle cells are elongated (muscle cell = muscle fiber)
Contraction of muscles is due to the movement (pulling together) of microfilaments (micro = “small”; fila = “thread”)

18. Smooth Muscle Characteristics
Lacks striations
Spindle-shaped cells
Single nucleus
Involuntary—no conscious control
Contractions happen very slowly
Found mainly in the walls of hollow organs
Stomach, urinary bladder, respiratory passages

19. Cardiac Muscle Characteristics
Striations
Usually has a single nucleus
Branching cells
Joined to another muscle cell at an intercalated disc
Involuntary
Contractions happen slowly
Found only in the heart

20. Skeletal Muscle Characteristics
Let’s look at our Muscle Tissue Comparison checklist…
Skeletal Muscle Characteristics
Most are attached by tendons to bones
Cells are multinucleated
Striated—have visible banding
Voluntary—subject to conscious control
Contractions happen slow to fast
Muscles are either contracted or relaxed
Contracted the muscle exerts pulling force = muscle shortens
Since muscles can only pull (not push), they work in pairs (antagonistic muscles)
Example: Biceps & Triceps
Muscle that bends joint is called the flexor muscle
Muscle that straightens joint is called the extensor muscle
Which is the flexor muscle?
Extensor muscle?

21. EXAMPLE
