Question 1

What are the parts of the typical muscle?

Answer 1

Belly: meaty fibrous part of the muscle
Attachment: tendon attachment
Origen: the less mobile
Intertion/termination: there can be multiple

Question 2

Types of muscles attachments

Answer 2

Fleshy:
Aponeurosis: sheet-like
Tendons: structures connect the muscle belly to a bone

Question 3

Sesamoid bones modify what?

Answer 3

Modify joint dynamics

Tend to be embedded in tendon to protect them from wear

Question 4

What are synovial bursae?

Answer 4

Viscous fluid that protects tendon as it passes over a point of friction
Bursa has a capsule with outer connective tissue & inner synovial membrane
It has an inner and outer membrane

Question 5

Where do tendon sheets go?

Answer 5

Over the tendons where a greater portion of the circumference is vulnerable

Question 6

What are the layers of tendon sheets?

Answer 6

Parietal surface/layer: away from the tendon (viscera)
Visceral layer: toward the tendon (viscera)
They are connected by mesotendon
The yellow space: potential space depends of what is going on it can fill with fluids and change in size. ex: congestive heart failure

Question 7

What are the associated structures of the muscle?

Answer 7

Fascia: connective tissue (CT) proper that binds the organs of the body together. It has a superficial (dermis) and deep layer (muscles). It holds the muscles together as a group
Use blunt probe to separate muscles and rapture deep fascia

Question 8

What is the Subserous?

Answer 8

It is the “glue” that supports serous membranes lining body cavities

Question 9

What is the carotid sheath?

Answer 9

It is part of the deep cervical fascia

Question 10

What is the plu: Retinacula (sin: Retinaculum)?

Answer 10

It is a thicker fascia: they are bands of connective tissue that holds tendons in place

Question 11

What is the Annular ligaments?

Answer 11

They surround the tendons going down the digit. Maintain efficiency for the tendons

Question 12

Accessory carpal bone why is it important?

Answer 12

Carpal tunnel syndrome

Question 13

Do muscles work individually?

Answer 13

No they operate in concert

Question 14

What is a prim mover and an agonist?

Answer 14

cooperating muscles

Question 15

Antoginist muscle is?

Answer 15

Oppose movement

Question 16

What is a synergist muscle?

Answer 16

Modify action

Question 17

What is a fixator muscle?

Answer 17

prevent rather than promote movement

Question 18

What are the muscles of the cubital joint?

m. = singular
mm. = plural

Answer 18

Bicepts brachii (prime mover): flexes the joint and extends the humeral joint
Brachialis (agonist)
Tricepts brachii (antagonist) caudal aspect of the brachium. It has four heads and it is a major extensor muscle
ex: during seizures legs get stiff and shaking bc they brain is sending signals to both agonist and antagonist muscles
Deltoideus: flexor of the humeral joint (antagonist) smooth out the movement
Biceps brachii: at the humeral joint may serve as synergist

Question 19

Extrinsic muscles do what?

Answer 19

Connect the muscle to the body wall

Question 20

What are the groups of extrinsic muscles?

Answer 20

Serratus ventralis: serrated face attachment. It goes to three different regions
Origen: ventralis cervics, ventralis thoracis
Insertion: serrated face of the scapula
Action: elevates the trunk

Question 21

What is the Rhomboideus muscle?

Answer 21

Origen:

Rhomboideus thoracis=dorsal thorax, Rhomboideus capitis=dorsal neck

Question 22

What is the Rhomboideus muscle?

Answer 22

Origen:
Rhomboideus thoracis=dorsal thorax, Rhomboideus capitis=dorsal neck
Insertion: dorsal border of the scapula and/or cartilage
Action

Question 23

Intrinsic muscles do what?

Answer 23

Thoracic limb in dog and cat is solely connected to chest by muscle, not bone. Humans have the collar bone that connects limb to the chest.

Question 24

Intrinsic muscles do what?

Answer 24

Thoracic limb in dog and cat is solely connected to chest by muscle, not bone. Humans have the collar bone that connects limb to the chest.

Question 25

Spinal scapula is a big deal why?

Answer 25

Because you can palpate it and diagnose trauma injuries

Question 26

What are the attachments of the Trapezius?

Answer 26

Middorsal raphe

Spine of the scapula

Question 27

What is the function of the extrinsic Brachiocephalicus muscle?

Answer 27

It goes from the brachium (humerus upper arm) to the head (cephalicus)
Cleido: medical term for clavical and its different components

Question 28

What is the function of the Omostransversarius?

Answer 28

Omo: refers to shoulder
Transvesarius: across vertebrae
*Most mammals have 7 cervical vertebrae
It goes from C1 (Atlas) to shoulder (scapula)
It can be seen after Brachiocephalicus is reflected
Action: pull thoracic limb cranially (and/or) depress and pull head and neck laterally

Question 29

Latissimus dorsi

Answer 29

Thoracolumbar fascia
Teres major tuberosity of the humerus
It is a flat sheet-like muscle

Question 30

Pectoral muscles

Answer 30

They are under the adipose tissue of the chest
-Superficial vs. Deep pectoral
Superficial: adducts the thoracic limb
Deep: adducts thoracic limb

Serratus ventralis muscle

Answer 31

Thoracic part
Cervical part
Origen: serrated face of scapula
Insertion: ribs
