What runs through clavipectoral fascia?
The arterial pedicles used for rotation of the pectoralis major muscle are the pectoral branch of the thoracoacromial artery, the lateral thoracic artery, and the superior thoracic artery. These vessels pass through the clavipectoral fascia to enter the muscle on its deep surface.
What is clavipectoral fascia in anatomy?
The clavipectoral fascia is a sheet of loose connective tissue which is the deep layer of fascia in the pectoral region. It acts to suspend the floor of the axilla.
Where is the clavipectoral fascia attached?
Traced upward, it splits to enclose the subclavius, and its two layers are attached to the clavicle, one in front of and the other behind the muscle; the deep layer fuses with the deep cervical fascia and with the sheath of the axillary vessels….

What is the function of pectoral fascia?
The pectoral fascia is a thin layer of tissue that covers the pectoralis major and minor muscles. Its function is to wrap the two muscles and allow them to glide smoothly when contracting.
What is the purpose of Deltopectoral groove?
The deltopectoral groove is an indentation in the muscular structure between the deltoid muscle and pectoralis major. It is the location through which the cephalic vein passes and where the coracoid process is most easily palpable.
What are three main functions of the fascia of skeletal muscles?
Functional Fascia It surrounds tissues and provides shape for muscles, tendons, and joints. But it also can help with functional movement by reducing friction between structures. Fascia provides moveable wrappings around muscles, tendons, and nerves.
What are the branches of the axillary artery in Clavipectoral triangle?
Second (retropectoral) part. The second part of the axillary artery has two branches: thoracoacromial artery: runs over pectoralis minor to pierce the clavipectoral fascia and supply the clavicle, deltoid, acromion and pectoralis muscles via its four terminal branches.
What is Costoclavicular ligament?
The costoclavicular ligament, also known as the rhomboid ligament or Halsted’s ligament, is a ligament of the shoulder girdle. It is short, flat, and rhomboid in form. It is the major stabilizing factor of the sternoclavicular joint and is the axis of movement of the joint, especially during elevation of the clavicle.
How can fascia affect the function of the muscle?
Fascia supports structures in your body. It surrounds tissues and provides shape for muscles, tendons, and joints. But it also can help with functional movement by reducing friction between structures. Fascia provides moveable wrappings around muscles, tendons, and nerves.
What does stretching do to fascia?
How does your stretching technique work through fascia stiffness? The Bendable Body Method stretches the fascia with resistance and tension, allowing the tissue to regenerate and keeping it springy and supple, which helps you feel stronger, more energetic, more flexible, and more agile.
What is in the clavipectoral triangle?
It contains the cephalic vein, and deltopectoral fascia, which is a layer of deep fascia that invests the three structures that make up the border of the triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle, giving branches to both the deltoid and pectoralis major muscles.
What forms the clavipectoral triangle?
trigonum clavipectorale) is an anatomical triangle bordered by the following structures: pectoralis major muscle; deltoid muscle; clavicle.
What is Deltopectoral groove?
The deltopectoral groove is an indentation in the muscular structure between the deltoid muscle and pectoralis major. Deltopectoral groove. Deltoid muscle. Pectoralis major. TA2.
What are the contents of the deltopectoral triangle?
Fun Fact: Deltopectoral Triangle
- Contains the cephalic vein, pectoral nerves and pectoral artery (a branch of thoracoacromial trunk).
- Provides surgical access to the genohumeral (shoulder) joint, sparing adjacent muscles.
- Serves as a landmark for percutaneous infra-clavicular cannulation of the subclavian vein.
Where does costoclavicular ligament attach?
The costoclavicular ligament binds the inferior medial clavicle (via the rhomboid fossa) to the first costal cartilage and the adjacent end of the first rib. It is composed of an anterior lamina and posterior lamina which are usually separated by a bursa.
What is the clavipectoral fascia?
Clavipectoral fascia. Below this it is thin, and at the upper border of the pectoralis minor it splits into two layers to invest the muscle; from the lower border of the pectoralis minor it is continued downward to join the axillary fascia, and lateralward to join the fascia over the short head of the biceps brachii . The coracoclavicular fascia…
How many layers of fascia are attached to the clavicle?
Traced upward, it splits to enclose the subclavius, and its two layers are attached to the clavicle, one in front of and the other behind the muscle; the deep layer fuses with the deep cervical fascia and with the sheath of the axillary vessels.
What is theclavipectoral fascia?
Theclavipectoral fascia is a sheet of loose connective tissue which is the deep layer of fascia in the pectoral region. It acts to suspend the floor of the axilla.
Where does the pectoralis minor join the axillary fascia?
Below this it is thin, and at the upper border of the pectoralis minor it splits into two layers to invest the muscle; from the lower border of the pectoralis minor it is continued downward to join the axillary fascia, and lateralward to join the fascia over the short head of the biceps brachii .
