What inserts on the ulnar tuberosity?
The ulnar (or brachial) tuberosity is a roughened depression immediately inferior to the coronoid process. It marks the insertion of the brachialis muscle, a flexor of the elbow that originates from the anterior surface of the humerus.
Where is the tuberosity of ulna located?
The tuberosity of the ulna is a rough eminence on the proximal end of the ulna. It occurs at the junction of the antero-inferior surface of the coronoid process with the front of the body.
What muscles attach to the tuberosity of the ulna?
Just below the coronoid process at the highest point of the shaft, the ulnar tuberosity forms the muscular attachment of the brachialis muscle….Ulnar shaft
- The abductor pollicis longus muscle,
- The extensor pollicis longus muscle and.
- The extensor indicis muscle.
Which bone marking is the radial tuberosity?
|Projection from the lateral surface of the distal wend of the ulna||Styloid process|
|Rounded proximal end of the radius||Head|
|Roughened area on the anterior/medial surface distal to the head||Radial tuberosity|
|Located on medial surface of distal end of the radius||Ulnar notch|
Where is the deltoid tuberosity?
The deltoid tuberosity of the humerus lies proximally about a third of the way to the elbow and provides an attachment point for the deltoid muscle. The deltoid is a triangular muscle with three attachment points: the humerus, the clavicle, and the scapula.
What attaches to radial and ulnar tuberosity?
radius. …is a rough projection, the radial tuberosity, which receives the biceps tendon. A ridge, the interosseous border, extends the length of the shaft and provides attachment for the interosseous membrane connecting the radius and the ulna.
What is the significance of the radial tuberosity?
The radial tuberosity contributes to the biceps supination moment arm and the elbow flexion moment. The purpose of our study was to compare the impact of a cortical bone trough versus an anatomic repair on measurements of the forearm supination moment arm and elbow flexion force efficiency.
What attaches to the radial tuberosity?
Biceps brachii attaches to the radial tuberosity.
What is a 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 inserts on deltoid tuberosity?
|Origins||Lateral 1/3 of Clavicle (clavicular part), Acromion (acromial part), Spine of Scapula (spinal part) Mnemonic: ‘Deltoid helps you carry SACS’|
|Insertion||Deltoid tuberosity of humerus|
|Innervation||Axillary nerve (C5, C6)|
What is the meaning of deltoid tuberosity?
In human anatomy, the deltoid tuberosity is a rough, triangular area on the anterolateral (front-side) surface of the middle of the humerus. It is a site of attachment of deltoid muscle.
What is the tuberosity of the ulna?
The tuberosity of the ulna is a rough eminence on the proximal end of the ulna. It occurs at the junction of the antero-inferior surface of the coronoid process with the front of the body. It provides an insertion point to a tendon of the brachialis (the oblique cord of the brachialis is attached to the lateral border).
What is the ulna prominence?
tu·ber·os·i·ty of ul·na. a prominence at the lower border of the anterior surface of the coronoid process, giving attachment (insertion) to the brachialis muscle.
What is the ulnar notch of the radius?
The ulnar notch of the radius is a medial concavity upon the distal head of the bone which directly contacts the distal ulna at the same level. The ulna is a long bone that helps stabilize the antebrachial region from the medial side of the forearm. Its proximal end consists of the following processes (2) and notches (2):
What is anterior aspect of the ulna?
Anterior aspect. Tuberosity of the ulna. [edit on Wikidata] At the junction of the antero-inferior surface of the coronoid process with the front of the body is a rough eminence, the tuberosity of the ulna (or ulnar tuberosity), which gives insertion to a part of the Brachialis; to the lateral border of this tuberosity the oblique cord is attached.
