What are the Axioappendicular muscles?

What are the Axioappendicular muscles?

The Axioappendicular muscles are the muscles that extend between the axial and (superior or inferior) appendicular skeletons. There are two groups, the anterior axioappendicular muscles and the posterior axioappendicular muscles….Axioappendicular muscles

  • Pectoralis major.
  • Pectoralis minor.
  • Subclavius.
  • Serratus anterior.

What are the 4 anterior Axioappendicular muscles?

The anterior axio-appendicular group is composed of four muscles: the pectoralis major, pectoralis minor, the subclavius, and the serratus anterior. The pectoralis major is a relatively flat, fan shaped muscle, which covers the upper half of the thorax. This muscle has two proximal attachments also called heads.

Which part of the upper limb consists of 5 cylindrical bones?

It is composed of five metacarpal bones (metacarpals). Each metacarpal consists of a base, shaft, and head. The proximal bases of the metacarpals articulate with the carpal bones, and the distal heads of the metacarpals articulate with the proximal phalanges, and form the knuckles of the hand.

What is the upper limb composed of?

The upper extremity or arm is a functional unit of the upper body. It consists of three sections, the upper arm, forearm, and hand. It extends from the shoulder joint to the fingers and contains 30 bones. It also consists of many nerves, blood vessels (arteries and veins), and muscles.

What muscle is in chest?

pectoralis major
Pectoralis muscle, any of the muscles that connect the front walls of the chest with the bones of the upper arm and shoulder. There are two such muscles on each side of the sternum (breastbone) in the human body: pectoralis major and pectoralis minor.

What are the seven Scapulohumeral muscles?

The scapulohumeral muscles are a group of seven muscles that connect the humerus to the scapula….

  • pronator teres.
  • palmaris longus.
  • flexor carpi radialis.
  • flexor carpi ulnaris.
  • flexor digitorum superficialis.

What muscle is in the upper arm?

The pectoralis major, latissimus dorsi, deltoid, and rotator cuff muscles connect to the humerus and move the arm. The muscles that move the forearm are located along the humerus, which include the triceps brachii, biceps brachii, brachialis, and brachioradialis.

What are the 3 major leg bones?

The bones of the human leg, like those of other mammals, consist of a basal segment, the femur (thighbone); an intermediate segment, the tibia (shinbone) and the smaller fibula; and a distal segment, the pes (foot), consisting of tarsals, metatarsals, and phalanges (toes).

What is the upper limb bone?

There are 30 bones in each upper limb. The humerus is the single bone of the upper arm, and the ulna (medially) and the radius (laterally) are the paired bones of the forearm.

What does the upper limb do?

In humans, each upper limb is divided into the arm, forearm and hand, and is primarily used for climbing, lifting and manipulating objects.
