Openings in the Diaphragm

25
Q

The center of the diaphragm is composed of this sheet of tendon.

A

Central Tendon

26
Q

These muscles tend to be arranged in several layers, with the muscle fibers of each layer running at different angles.

  • This makes for a strong, supportive structure to enclose and protect the abdominal organs.
A

Abdominal Muscles

27
Q

Often categorized by their general location:

  • Anteromedial
  • Anterolateral
  • Posterior Abdomen
A

Abdominal Muscle Categories

28
Q

One of the anteromedial muscles and runs from the sternum and rib cage straight down to the pubic bone.

A

Rectus Abdominus

29
Q

Run at angles down the anterior lateral part of the abdomen, with the transverse muscles underneath them.

A

External and Internal Oblique

30
Q

An important posterior abdominal muscle. Runs from the lumbar vertebrae down to the femur. Involved with moving the femur and serves as an anatomical guide along the medial border for the external iliac artery and vein.

A

Psoas Major

31
Q

Comes from the latin word for “Trapezoid Shaped.” This is located in the upper back and actually runs from the back of the occipital bone, down the thoracic vertebrae, and over to the acromion of the scapula.

A

Trapezius

32
Q

The superior lateral projection of the scapula.

A

Acromion

33
Q

comes from the Lain word for “wide” and “back.” A large, lower back muscle, which is attached to the humerus and is involved in its movement.

A

Latissimus Dorsi

34
Q

A group of muscles in the back, which run vertically from thee lower back area up to the more superior vertebrae and ribs. Primarily involved with movement of the vertebral column and help keep the spine in an erect position.

A

Erector Spinae

35
Q
  • Deltoid
  • Teres Major Muscle
  • Coracobrachilalis
  • Brachialis
  • Biceps Brachii
  • Triceps Brachii
  • Brachioradialis
  • Felxor Carpi Radialis
  • Flexor Carpi Ulnaris
  • Flexor Digitorium Superficialis
A

Upper Extremity and Shoulder Muscles

36
Q

A large, trianglur shaped muscle making up most of the mass of the shoulder area. Mainly involved in abduction of the humerus.

A

Deltoid

37
Q

Runs from the scapula to the upper part of the humerus. Involved in movements of the upper arm.

  • Serves as the point at which the axillary artery terminates and becomes the brachial artery.
A

Teres Major Muscle

38
Q

Located in the upper arm area. Named for it’s point of attachment. Moves the arm and serves as the anatomical guide for the axillary artery, which is located just behind it’s medial border.

A

Coracobrachialis

39
Q

Flexors of the anterior surface of the elbow joint.

A

Brachialis and Biceps Brachii

40
Q

Located on the back of the humerus and extends the elbow joint.

A

Triceps Brachii

41
Q

Located in the superior lateral part of the forearm and assists the brachialis and the biceps brachii muscles in flexing the forearm.

A

Brachioradialis

42
Q

Act to flex the wrist. The tendons of these muscles, in the wrist area, serve as important anatomical guides in locating the radial and ulnar arteries, which lie just lateral to the respective tendons.

A

Flexor Carpi Radialis and Flexor Carpi Ulnaris

43
Q

Has to do with flexing the digits (fingers).

A

Flexor Digitorum Superficialis

44
Q
  • Gluteus Maximus
  • Quadriceps
  • Sartorius
  • Adductor Longus
  • Adductor Magnus
  • Hamstrings
  • Popliteus
  • Tibialis Anterior
  • Gastronemius
  • Soleus
A

Muscles of The Lower Extremities

45
Q

Makes up the bulk of the buttocks area, and is important for its action of extending the thigh.

A

Gluteus Maximus

46
Q

Includes the rectus femoris and the three vastus muscles. Serve to extend the lower leg at the knee joint.

A

Quadriceps

47
Q

On the anterior surface of the thigh. A superficial, strap-like muscle running obliquely across the thigh to the inner side of the knee area.

  • Lateral Boundary of the Femoral Triangle
A

Sartorius

48
Q

Serves as an important anatomical guide in locating the femoral vessels, which run through the center of this triangular area.

A

Femoral Triangle

49
Q

Superior Boundary of the femoral triangle.

A

Inguinal Ligament

50
Q

Medial boundary of the femoral triangle.

A

Later border of the adductor longus muscle.

51
Q

Lateral boundary of the femoral triangle.

A

Medial border of the Sartorius Muscle

52
Q

On the medial side of the thigh. This is the medial boundary of the femoral trangle.

A

Adductor Longus

53
Q

Contains a canal-like opening, called the adductor canal (Hunter’s canal), through which the femoral vessels and nerves pass. This openeing also serves as the point at which the femoral artery terminates and becomes known as the popliteal.

A

Adductor Magnus

54
Q

These muscles flex the lower leg.

A

Hamstrings

55
Q
  • Biceps femoris
  • Semitendinous
  • semimembranous
A

Muscles of the Hamstrings

56
Q

At the base of the popliteal space, running at an angle from the borrom of the femur to the top of the tibia.

  • The inferior border of this muscle marks the point at which the popliteal artery termines by bifurcating into the anterior and posterior tibial arteries.
A

Popliteus

57
Q

Located in the front of the leg.

A

Tibialis Anterior

58
Q

Muscles in the posterior lower leg, or calf area. Both of these attach to the hell bone (calcaneus). Have to do with extending the foot, thus allowing you to “stand on your toes.”

A

Gastrocnemius And Soleus Muscles

59
Q

The strong tendon that connects the gastrocnemius to the soleus muscles.

A

Cancaneal Tendon (Achilles Tendon)
