What is a bicipital groove?
What is a bicipital groove?
The bicipital groove is an indentation that lies along the anterior aspect of the proximal humerus and contains the tendon of the long head of the biceps brachii muscle (fig. 1 ).
What is the bicipital groove formed by?
biceps brachii muscle
The bicipital groove (intertubercular groove, sulcus intertubercularis) is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle. It allows for the long tendon of the biceps brachii muscle to pass….

What travels in the bicipital groove?
The greater and lesser tubercles of humerus are separated from each other by a deep groove, the intertubercular groove (bicipital groove), which lodges the long tendon of the Biceps brachii and transmits a branch of the anterior humeral circumflex artery to the shoulder-joint.
What is the meaning of Bicipital?
1 of muscles : having two heads or origins. 2 : of or relating to a biceps muscle.
How does a bicipital groove feel?
On one side, locate the greater tuberosity by palpating inferiorly from the acromion. Keep the fingers of one hand at this level and use the other to externally rotate the arm at the shoulder. As the arm rotates, sequentially the greater tuberosity, bicipital groove and lesser tuberosity are felt.
When do you palpate the bicipital groove?
Place your index finger on one tubercle and the ring finger of the same hand on the other tubercle. The middle finger of the same hand is placed in between the other two fingers to palpate the area of the biciptal groove. The tendon of the long head of the biceps brachii is located in this groove.
What accompanies the brachial artery in the medial bicipital groove?
The branches arising from this portion of the brachial artery include the nutrient artery to the humerus, muscular branches, and superior ulnar collateral artery, which accompanies the ulnar nerve to the groove on the posterior surface of the medial epicondyle.
Where is the radial groove?
humerus bone
The radial sulcus ( also known as the musculospiral groove, radial groove, or spiral groove) is a broad but shallow oblique depression for the radial nerve and deep brachial artery. It is located on the center of the lateral border of the humerus bone.
Where is the greater tubercle?
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. 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 Bicipital tenosynovitis?
Bicipital tenosynovitis is inflammation of the biceps tendon and its surrounding tendon sheath just below its attachment on the front part of the scapula (shoulder blade).
What does an X-ray Tech do to show the shoulder and humerus?
This article discusses radiographic positioning for the Radiologic Technologist (X-Ray Tech) to show the shoulder and humerus. Purpose and Structures Shown: This view should demonstrate the bones and soft tissue of the upper arm, specifically the full length of the humerus, elbow and shoulder joints, and epicondyles without rotation.
What is the normal angle of a central ray for shoulder pain?
Central ray: The central ray should be 5-15 degrees laterally traversing the shoulder joint and toward the area of the elbow. Shoulder Inferosuperior Axial (4 variations)
What are the different types of imaging tests for biceps tendons?
Imaging Tests 1 X-rays. Although x-rays cannot show soft tissues like the biceps tendon, they can be useful in ruling out other problems… 2 Magnetic resonance imaging (MRI). These scans create better images of soft tissues. They can show both partial and… More
Where does the rotator cuff attach to the biceps?
These tissues are called the rotator cuff. They cover the head of your upper arm bone and attach it to your shoulder blade. The upper end of the biceps muscle has two tendons that attach it to bones in the shoulder. The long head attaches to the top of the shoulder socket (glenoid).
