General consideration on Skeletal Muscle

Question 1

Faster and more forceful movement can be created by…

Motor proteins

Question 2

What are the three types of muscles?

Answer 2

Skeletal, Cardiac, Smooth

Question 3

What is the origin of a muscle?

Answer 3

The stable part (nonmoving)

Question 4

What is the muscle belly?

Answer 4

Part that contracts

Question 5

What is the Insertion of a muscle?

Answer 5

The distal part that moves

Question 6

Classification: does 1 action?

Answer 6

Agonist

Question 7

Classification: opposite action and give an example.

Answer 7

Antagonist
example: bicep, tricep

Question 8

Classification: can help one another (agonist work in this manner). replace one another during damage.

Answer 8

Synergistic

Question 9

Classification: Doesn’t create action but stabilizes the region.

Answer 9

Fixator

Question 10

Name and description

Answer 10

Fusiform
Description: muscle belly, short tendon (proximal) and long tendon (distal)

Question 11

Name and description

Answer 11

Unipennate.
Description: long tendon at 1 side and muscle fiber on 1 side

Question 12

Name and description

Answer 12

Bipennate.
Description: single tendon in middle and muscle fiber on each side

Question 13

Answer 13

Bicep, Tricep, Quadricep

Question 14

Name and description

Answer 14

Digastric/ Biventer.
Description: 2 muscle belly’s ( fusiform) and a tendon between

Question 15

Answer 15

Broad (flat)

Question 16

Answer 16

Serrate (comb teeth). aka strap muscle attached to end.

Question 17

Whats the shape like and example.

Answer 17

Strap. ribbon shaped in abdomen

Question 18

Answer 18

Cruciate

Question 19

Answer 19

Spiral

Question 20

Name, type of muscle, type of movement, and example.

Answer 20

Sircular/ Sphinteric.
Strap muscle.
Voluntary movement.
In genital region example: rectum.

Question 21

Explain classification by arterial supply. Reconstructive surgery.

Answer 21

When part of the tissue is lost we must reconstruct the tissue by using a viable tissue (with vascular support). It is supplied from the artery and drained to the vein. We must preserve the artery of a muscle and attach the artery to another artery to fill the tissue gap.

Question 22

How is the fascia designed?

Answer 22

Bone-Periosteum-Muscle-Deep fascia-Superficial fascia- Skin

Question 23

What is Periosteum?

Answer 23

the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal

Question 24

What does deep fascia do?

Answer 24

Covers the entire skeletal muscle

Question 25

What are the 2 layers of the superficial fascia?

Answer 25

1. superficial layer: lots of room for adipose tissue
2. close to deep fascia: no adipose tissue

Question 26

Where are the superficial nerve, veins, arteries, etc located? Any exception?

Answer 26

In the deep layer and not seen in the superficial fatty tissue. There are exceptions like superficial veins (arm).

Question 27

Where are the facial muscles located?

Answer 27

Superficial fascia

Question 28

Which muscles aren’t covered by deep fascia?

Answer 28

Facial muscles

Question 29

What is a compartment?

Answer 29

Muscles that have the same/similar function are in a single room of fascia.

Question 30

Does a compartment have a limit and how does a vein enter?

Answer 30

Compartment is a confined space. Veins pass through a section of the deep fascia and supply the structure (only entrace to compartment)

Question 31

What is compartment syndrome

Answer 31

Increasing the pressure in the compartment due to bleeding of the vein. Since the deep fascia has little flexibility its main function is to keep the muscle in shape. Therefore, any muscular nerve, tissue, or vessel that arrives will be blocked and tissue starts to die.
