What is the radial groove of the humerus?
The radial (or spiral) groove is a shallow depression that runs diagonally down the posterior surface of the humerus, parallel to the deltoid tuberosity. The radial nerve and profunda brachii artery lie in this groove.
Where is the radial nerve located?
axilla
The radial nerve is one of the terminal branches of the posterior cord. In the axilla, it lies behind the axillary and upper brachial arteries and passes anterior to the tendons of teres minor, latissimus dorsi and subscapularis.
What does the radial groove contain?
the shallow groove that passes around the shaft of the humerus; it lies between the humeral attachments of the lateral and medial heads of the triceps brachii; the radial nerve and deep brachial artery course within the groove.
Where is the radial groove in the arm?
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. Cross-section through the middle of upper arm.

Where is the radial sulcus located in the body?
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. Intertubercular groove. Triceps brachii muscle.
Where does the radial nerve pass through the body?
Radial nerve. The radial nerve passes through the humerus spiral groove and the arch formed by the attachment of the humerus and triceps. It also passes through the lateral intermuscular septum and the Arcade of Frohse. This is located below the elbow but above the supinator.
