What else can I help you with?
What articulate with the ulna and scapula?
This is called as elbow joint. It is a synovial type of joint. It is actually a joint between humerus and ulna mainly. The radius takes part in the joint passively. This is hinge variety of joint.
What is the origin and insertion point for the deltoids?
The deltoid is very interesting muscle. It arise from the outer and lateral border of the clavicle and outer and lateral border of the spine of the scapula. From the corresponding inner border, you have insertion of the trapezius muscle. The deltoid muscle is inserted on the deltoid tuberosity on the lateral and middle part of the humerus bone. So it looks that the trapezius muscle continue as the deltoid muscle.
Where do most fractures of the humerus occur?
Most fractures of the humerus occur in the middle of the bone, around the area of the shaft known as the diaphysis. This is due to the vulnerability of this part of the bone to direct trauma.
Is the foot located proximal to the leg?
No, the foot is distal to the leg. The foot is the most distal part of the lower extremity, located furthest away from the body, while the leg is the proximal segment of the lower limb.
First part of bowel distal to the stomach?
The first part of the bowel distal to the stomach is the duodenum. It is the shortest and widest part of the small intestine and plays a critical role in the absorption of nutrients.
Can the most lateral part of the humerus be felt through the skin?
Yes, the most lateral epicondyle, the most lateral part of the humerus, can be felt through the skin. It's the bump at the elbow on the thumb side.
Is The distal end of the humerus at the shoulder?
The distal end of the humerus articulates with the two bones of the forearm, the radius and the ulna. Noteworthy features on its distal and are the lateral and medial epicondyles (one of which is your elbow) as well as the trochlea and capitulum(both of these features forming the "pulley" shape found at the end of the humerus.
What part of the humerus forms the lateral contour of the shoulder?
The greater tuberosity of the humerus forms the lateral contour of the shoulder. The supraspinatus muscle attaches at the greater tuberosity.
What bony landmark of the anterior humerus articulates with the ulna?
To you mean the joint itself? The elbow, AKA the proximal-distal axis of the humerus and ulna, respectively.Or just the distal epiphysis of the humerus (the rounded head of the bone which is farther fromthe arm's point of attachment to the torso)
What is a fracture of the distal end of the fibula?
A fracture of the distal end of the fibula, known as a lateral malleolus fracture, typically occurs at the ankle joint. It is commonly caused by twisting or direct impact to the ankle. Treatment may involve immobilization with a cast or surgery, depending on the severity of the fracture.
What is the difference between lateral and distal?
Lateral refers to a left-to-right relationship, eg, the left lung is lateral to the right lung.Distal refers to a near-far or base-tip relationship. The fingertip is distal; the base of the finger is proximal.
What articular surfaces make up the shoulder joint?
The proximal surface is the acromion of the scapula while the distal part is the head of the humerus.
What joint is formed by the humerus?
The distal (meaning furthest from the body) aspect of the humerus that forms the elbow is called the trochlea, which literally means pulley.The distal & medial aspect of the humerus in the region of the elbow is called the medial epicondyle, but this is more of a site for tendon attachment for flexor muscles. The medial epicondyle is not a part of the actual elbow joint.
What directional terms refers to body parts further away from a reference point?
Lateral is a positional term that means away from the midline of the body.
What two bones articulate with the distal humerus?
The ulna and the radius articulate with the distal humerus at the elbow joint. The ulna forms the primary articulation, while the head of the radius articulates with a small depression on the side of the ulna known as the radial notch.
What articulate with the ulna and scapula?
This is called as elbow joint. It is a synovial type of joint. It is actually a joint between humerus and ulna mainly. The radius takes part in the joint passively. This is hinge variety of joint.
Part of the elbow is formed by the?
Part of the elbow is formed by the humerus bone from the upper arm and the ulna and radius bones from the forearm. These bones come together to create the joint that allows for flexion and extension of the arm.
