What bone articulates with the trochlear notch?
humerus
In the same way, what bone aligns with the radial-notch?
Ulna
What bone also connects with the trochlea of the Humerus? Trochlea of the humerus. The humeral trochlea is the medial part of the articular surface at the elbow joint. It connects to the trochlear groove on the forearm.
You might also wonder where the Trochlear notch is located.
Ulna
Is the entire Trochlear Nose an articular surface.
To fit the capitulum, the upper surface of the cylindrical head radius is spherically concave. The deep trochlear hole is visible at the upper end of the Ulna. The trochlear nose has two distinct articular surfaces, one on each side of the coronoid process and one on the olecranon.

How many bones are in the human body?
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.
What does the Trochlear notch do?
The trochlear notch (semilunar notch, greater sigmoid cavity) is a large depression, formed by the olecranon and the coronoid process, and serving for articulation with the trochlea of the humerus.
Where is the radial notch found?
Radial Notch of the Ulna. The radial notch is found on the ULNA and articulates with the head of the radius to form a pivot joint. It is located to the lateral side of the coronoid process.
What bones does the radius articulate with?
The radius articulates proximally at the elbow with the capitulum of the humerus and the radial notch of the ulna. It articulates at its distal end with the ulna at the ulnar notch and with the articular surfaces of the scaphoid and lunate carpal bones.
What does the ulnar notch articulate with?
The articular surface for the ulna is called the ulnar notch (sigmoid cavity) of the radius; it is in the distal radius, and is narrow, concave, smooth, and articulates with the head of the ulna forming the distal radioulnar joint.
What is forearm bone called?
Our forearm contains two long, parallel bones: the ulna and the radius. The end of the ulna, known as the olecranon, extends past the humerus and forms the bony tip of the elbow. At its distal end, the ulna forms the wrist joint with the radius and the carpals.
What is the only bone in your head that can move?
Your lower jawbone is the only bone in your head you can move. It opens and closes to let you talk and chew food. Your skull is pretty cool, but it's changed since you were a baby. All babies are born with spaces between the bones in their skulls.
What bone is the ulna?
The ulna is located on the opposite side of the forearm from the thumb. It joins with the humerus on its larger end to make the elbow joint, and joins with the carpal bones of the hand at its smaller end. Together with the radius, the ulna enables the wrist joint to rotate.
How many Scapulas do we have?
The scapula is ossified from 7 or more centers: one for the body, two for the coracoid process, two for the acromion, one for the vertebral border, and one for the inferior angle.
Where is the Trochlear nerve located?
The nucleus of the trochlear nerve is located in the caudal mesencephalon beneath the cerebral aqueduct. It is immediately below the nucleus of the oculomotor nerve (III) in the rostral mesencephalon.
Where is the Coronoid process located?
The coronoid process is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and of considerable strength. Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus.
What type of joint is the elbow?
hinge joint
What is carpal bone?
The carpal bones are the eight small bones that make up the wrist (or carpus) that connects the hand to the forearm. The term "carpus" is derived from the Latin carpus and the Greek καρπός (karpós), meaning "wrist". The carpal bones allow the wrist to move and rotate vertically.
What is the olecranon process?
1. olecranon process - process of the ulna that forms the outer bump of the elbow and fits into the fossa of the humerus when the arm is extended. olecranon. appendage, outgrowth, process - a natural prolongation or projection from a part of an organism either animal or plant; "a bony process"
What is Trochlear groove?
A slippery substance called articular cartilage covers the ends of the femur, trochlear groove, and the underside of the patella. Articular cartilage helps your bones glide smoothly against each other as you move your leg. (Left) The patella rests in a small groove at the end of the femur called the trochlear groove.
What does the Coronoid process articulate with?
trochlea of the humerus
Where is the glenoid cavity located?
The glenoid cavity or glenoid fossa of scapula is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula.
