The olecranon (/ oʊˈlɛkrənɒn /, from Greek olene 'elbow' and kranon 'head'), is a large, thick, curved bony process on the proximal, posterior end of the ulna. It forms the protruding part of the elbow and is opposite to the cubital fossa or elbow pit (trochlear notch).
The olecranon (olecranon process) is the large, superior projection on the proximal part of ulna. It curves anteriorly at its top, forming a prominent tip which is accommodated by the olecranon fossa of humerus during forearm extension.
1 Οκτ 2024 · Important landmarks of the proximal ulna are the olecranon, coronoid process, trochlear notch, radial notch and the tuberosity of ulna: Olecranon – a large projection of bone that extends proximally, forming part of trochlear notch. It can be palpated as the ‘tip’ of the elbow.
30 Οκτ 2023 · It bears the olecranon, trochlear notch, coronoid process, radial notch, sublime tubercle and ulnar tuberosity. The olecranon is a prominent, proximal projection from the posterior aspect of the proximal ulna and serves as the point of insertion for the triceps brachii muscle.
24 Ιουλ 2023 · Beginning with the sites around the elbow, the ulna has a bony process called the olecranon process. It is a thick, curved distinction at the proximal and posterior end and is bent forward. This trait allows the bone to fit into the olecranon fossa of the humerus.
18 Απρ 2022 · The olecranon articulates with the humerus via the olecranon fossa on the humerus, which is situated over the posterior surface of the humerus. It is continuous with the coronoid process of the ulna via the trochlear or semilunar notch anteriorly.
30 Οκτ 2023 · The coronoid process is the smaller of two projections located on the proximal end of the ulna. The larger projection is called the olecranon. The coronoid process is pyramid-shaped and it projects anteriorly. It has a base, apex and four surfaces.
