Chapter 15/16

Question 1

Muscle is covered by a whole course she covers the perimysium

Answer 1

Epimysium

Question 2

Group of skeletal muscle fibers that are bound together into bundles by tougher connective tissue it is covering the whole

Answer 2

Perimysium

Question 3

Controls the main movement of a muscle performs a specific movement

Answer 3

Prime mover

Question 4

Muscles that contract at the same time as the prime mover, helper muscle

Answer 4

Synergist

Question 5

Directly opposes the prime mover what

Answer 5

Antagonist

Question 6

Stabilizes movement

Answer 6

Fixator

Question 7

There the longest muscles including the sartorius they look strap like with parallel fascicles and are most typical
Example is the rectus abdominis

Answer 7

Parallel muscles

Question 8

Vesicles I radiate out from the small to have a wider point of attachment start wide and go narrow. Example is the pectoralis major

Answer 8

Convergent muscles

Question 9

Orbicular muscles and sphinctors they are often circle body tubes or openings. Example is orbicularis oris

Answer 9

Circular muscles

Question 10

Fascicles that may be close to parallel in the center or bounty of the muscle but covers one or both ends of the time example is the brachioradiallis

Answer 10

Fusiform muscles

Question 11

Fiber sent to us between the point of attachment example is the latissimus dorsi

Answer 11

Spiral muscles

Question 12

Feather like in appearance and their three different categories: unipennate bipennate and multipennate

Answer 12

Pennate muscles

Question 13

Point of attachment that does not move when the muscle contracts

Answer 13

Origin

Question 14

Point of attachment that moves when the muscle contracts

Answer 14

Insertion

Question 15

Tubelike tunnel around the tendon of a muscle that is lined with synovial membrane. It is a strong tough cord continuous at its other end with fibrous periosteum covering a bone

Answer 15

Tendon sheath

Question 16

Fibrous connective tissue found under the skin and surrounding deeper organs it holds the muscles together

Answer 16

Fascia

Question 17

It is any rigid bar free to turn about a fixed point also known as a fulcrum

Answer 17

Lever

Question 18

The lever lies between effort(pull) and resistance(load). Serves as stability

Answer 18

First class lever

Question 19

Strongest type. Load(resistance) Lies between fulcrum and joint at which effort(pull) is exerted

Answer 19

Second-class lever

Question 20

Most common. Produces mechanical disadvantage. Effort(pull) is closer to the fulcrum(balance) than resistance(load). It is always this way. Favors speed and range of motion over force.

Answer 20

Third-class lever

Question 21

Skeletal muscle cells or muscle fibers they are delicate connective tissue

Answer 21

Endomysium
