What are the four axial muscle groups?

These muscles of the anterolateral abdominal wall can be divided into four groups: the external obliques, the internal obliques, the transversus abdominis, and the rectus abdominis (Figure 1, Figure 2, and Table 1). Figure 1.

What is all about axial muscles?

The axial muscles are grouped based on location, function, or both. Some axial muscles cross over to the appendicular skeleton. The muscles of the head and neck are all axial. The muscles in the face create facial expression by inserting into the skin rather than onto bone.

What are the principal appendicular muscles?

10.6: Appendicular Muscles of the Pectoral Girdle and Upper Limbs

  • Muscles That Position the Pectoral Girdle.
  • Muscles That Move the Humerus.
  • Muscles That Move the Forearm.
  • Muscles That Move the Wrist, Hand, and Fingers. Muscles of the Arm That Move the Wrists, Hands, and Fingers. Intrinsic Muscles of the Hand.

What is the function of the axial muscles?

Axial muscles support and position the axial skeleton. Appendicular muscles support, move, and brace the limbs.

Is latissimus dorsi axial or appendicular?

The two axial muscles are the pectoralis major and the latissimus dorsi.

What is the principle muscle of the anterior neck?

Structure of the Anterior Cervical Region The anterior triangle is a region bounded superiorly by the inferior border of the mandible, laterally by the anterior median of the sternocleidomastoid muscle, and inferiorly by the jugular and clavicular notch of the manubrium.

Is the sphenoid axial or appendicular?

The cranial bones, including the frontal, parietal, and sphenoid bones, cover the top of the head. The facial bones of the skull form the face and provide cavities for the eyes, nose, and mouth. Although it is not found in the skull, the hyoid bone is considered a component of the axial skeleton.

What are the axial muscles of the trunk?

These sits-ups, along with other similar exercises, work our oblique (that is, not straight) as well as our rectus (or straight) muscles located in the body wall of our trunk. These oblique and rectus muscles are axial muscles, as they’re located in the middle, or the axis, of the body.

Are Carpals axial or appendicular?

It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.

Is sacrum axial or appendicular?

The axial skeleton together with the appendicular skeleton form the complete skeleton. Another definition of axial skeleton is the bones including the vertebrae, sacrum, coccyx, skull, ribs, and sternum.
