Examples of humerus in the following topics:
-
- The humerus is a bone in the upper arm.
- Distally, the humerus
articulates with the radius and ulna to form the elbow joint.
- The proximal portion of the humerus can be
divided into three parts.
- Finally, the greater and lesser tubercles are
found at the most superior end of the main shaft of the humerus.
- Distally, the humerus flattens to articulate
with the ulna and radius at the elbow joint.
-
- Humerus that act on the forearm are primarily involved in flexion and extension.
- The humerus is a long bone in the arm that
runs from the shoulder to the elbow.
- Attachments - Originates from
the scapula and attaches to the humerus.
- Attachments - Originates from
the humerus and attaches to the ulna.
- Diagram the movements of the humerus muscles that act on the forearm
-
- The shoulder or glenohumeral joint is a ball and socket joint formed between
the humerus and scapula.
- The muscle converges into a tendon attaching to the
humerus.
- Intrinsic muscles originate from the
scapula or clavicle and attach to the humerus.
- Attachments – Originates from
the posterior of the scapula and attaches to the humerus.
- Both attach
to the humerus.
-
- The scapula, or shoulder bone, is a flat, triangular bone that connects to the humerus and the clavicle.
- The
scapula also articulates with the humerus of the upper arm to form the shoulder
joint, or glenohumeral joint, at the glenoid cavity.
-
- The forearm contains two bones—the radius
and the ulna—that extend in parallel from the elbow, where they articulate with
the humerus to the wrist, where they articulate with the carpals.
- The cornoid process, together with the olecranon, forms the trochlear notch where it articulates with
the trochlea of the humerus.
- Proximally, the radius terminates with a disk-shaped head that articulates with the capitulum of the humerus and the radial notch of the
ulna.
-
- Attachments - Originates from
the humerus and attaches to the base of the hand.
- Attachments - Originates from
the humerus and attaches to the base of the digits.
- Attachments - Originates from
the humerus and attaches to the ulna.
- Attachments - Originates from
the humerus and attaches to the little finger.
- Attachments - Originates from the
humerus and attaches to the base of the hand.
-
- The humerus is the largest and longest bone of the upper limb and the only bone of the arm.
- The radius, located along the lateral (thumb) side of the forearm, articulates with the humerus at the elbow.
- It articulates with the humerus at the elbow.
- The upper limb consists of the humerus of the upper arm, the radius and ulna of the forearm, eight bones of the carpus, five bones of the metacarpus, and 14 bones of the phalanges.
-
- The main functions of the cuff are to stabilize the glenohumeral joint and rotate the humerus outward.
- In a typical case of a dislocated shoulder, a strong force that pulls the shoulder outward (abduction) or extreme rotation of the joint pops the ball of the humerus out of the shoulder socket.
- Doctors treat a dislocation by putting the head of the humerus back into the joint socket (glenoid fossa) of the scapula.
- X-ray of a complete tear of the supraspinatus resulting in a shift upwards of the head of the humerus.
-
- Upper arms
and forearms (6 bones) - Left and right humerus
(upper arm, 2), ulna
(2) and radius (2) (forearm)
- The three
regions of the upper limb arm (humerus), forearm (ulna medially and radius
laterally), and the hand.
-
- The force is applied at its point
of insertion on the ulna in the forearm, the elbow is the pivot, and the load is
the humerus in the upper arm.
- Internal rotation can also move the humerus and femur inward.
- External or lateral rotation is the opposite movement, pointing the distal portion of limbs as well as the humerus and femur away from the mid-line.
