Where is the greater tuberosity located?
Where is the greater tuberosity located?
The greater tuberosity is the “bump” of bone at the top of the humerus that serves as the attachment for two rotator cuff muscles. This attachment is why a fracture can also interfere with the functioning of the rotator cuff.
What muscles insert on the greater tuberosity?
Muscle Attachments
| Muscle | Attachment |
|---|---|
| Infraspinatus | Greater Tubercle |
| Teres Minor | Greater Tubercle Upper Part of the Lateral Border |
| Subscapularis | Lesser Tubercle |
| Pectoralis Major | Upper Part of the Anterior Border |
What is tuberosity in anatomy?
Tuberosity – A moderate prominence where muscles and connective tissues attach. Its function is similar to that of a trochanter. Examples include the tibial tuberosity, deltoid tuberosity, and ischial tuberosity. Tubercle – A small, rounded prominence where connective tissues attach.
What anatomical location is found between the greater and lesser tuberosity?
Between the greater tubercle and the lesser tubercle is the bicipital groove (intertubercular sulcus).
Where is the greater tuberosity of the femur?
The gluteal tuberosity is the lateral ridge above the linea aspera on the posterior surface of the femur. It is very rough surface. It runs almost vertically upward to the base of the greater trochanter.
Are tubercle and tuberosity the same thing?
Tubercle vs tuberosity A tubercle is a small rounded prominence, often a site of tendon or ligament attachment e.g. adductor tubercle of the femur. A tuberosity is larger, found in varying shapes and often rough in texture. The ulnar tuberosity is one example.
Which rotator cuff muscles attach to the greater tuberosity?
Supraspinatus: The supraspinatus muscle originates above the spine of the shoulder blade and inserts on the greater tuberosity of the humerus.
Is greater tuberosity the same as greater tubercle?
Discussing them further, the greater tuberosity of the humerus is a prominent area of the humerus at the top of the bone. It allows the attachment for two large, powerful rotator cuff muscles – supraspinatus and infraspinatus. Perhaps, it is known as the greater tubercle along with the lesser tubercle.
What is greater tuberosity fracture?
This condition is a fracture of the bony bump that is located opposite of the head of the humerus. This type of fracture can interfere with the rotator cuff.
What tendon attaches to greater tuberosity?
Greater tubercle of humerus
| Terminology | English: Greater tubercle of humerus Latin: Tuberculum majus humeri Synonyms: Greater tuberosity of humerus |
|---|---|
| Location | Lateral part of proximal end of humerus |
| Attachments | Supraspinatus, infraspinatus and teres minor muscles |
Where is the gluteal tuberosity?
The gluteal tuberosity (or line, crest, or ridge) is a long, wide, roughened, posterolaterally placed feature that extends from the base of the greater trochanter to the lateral lip of the linea aspera (see 12.1.
What inserts on greater tuberosity of humerus?
The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus.
What is the greater tuberosity of the shoulder?
Lennard Funk The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus. It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm outstretched.
What is the lateral surface of the greater tubercle?
Greater tubercle. The lateral surface of the greater tubercle is convex, rough, and continuous with the lateral surface of the body. Between the greater tubercle and the lesser tubercle is the bicipital groove (intertubercular sulcus).
What is a greater tuberosity fracture?
Greater Tuberosity Fractures. The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus. It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm…
What is the greater tuberosity of the humerus?
The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus.
