What is the region of the ulna that articulates with the humerus when the forearm is in full extension?

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 is the elbow region called?

The elbow region is anatomically referred to as the "cubital region." It is the area where the humerus, radius, and ulna bones meet, allowing for the movement of the forearm. The term "cubital" is derived from the Latin word "cubitus," meaning elbow. This region is important for various arm movements and activities.

The anatomic neck of the humerus is distal to the surgical neck of the humerus?

Actually, the anatomic neck of the humerus is proximal to the surgical neck of the humerus. The anatomic neck is the slightly constricted region below the head of the humerus, while the surgical neck is the region of the humerus prone to fractures located distal to the tubercles.

What is the difference of antebrachium and the brachium?

The antebrachium refers to the segment of the upper limb between the elbow and the wrist, containing the radius and ulna bones. The brachium, on the other hand, refers to the region between the shoulder and the elbow, which includes the humerus bone. In simple terms, the antebrachium is the forearm, while the brachium is the upper arm.

What is are latively shortregion between the forearm and the hand?

The relatively short region between the forearm and the hand is known as the wrist. It consists of a complex arrangement of bones, ligaments, and tendons that allow for a wide range of motion and flexibility. The wrist connects the radius and ulna of the forearm to the carpal bones of the hand, facilitating movements such as flexion, extension, and rotation.

How many bones make up your arm?

Upper arm: Humerus = 1 Forearm: Radius and ulna = 2 Wrist (carpal bones): Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate = 8 Metacarpals: 5 Phalangies: 14 (3 in every finger but only 2 in thumb) A grand total of 30!

What is the part of the arm between the wrist and elbow?

The upper - arm : humerus ; see related link below to additional information .

Anatomical name of the true elbow joint?

The elbow joint is a ginglymus, which is just another name for a hinge-joint. Three bones form the elbow joint: the humerus of the upper arm, and the paired radius and ulna bones of the forearm. The 'elbow' describes the region surrounding the elbow-joint. The bony bit at the very tip of the elbow is the upper end of the forearm ulna bone (if your arms are hanging downwards!) and is called the olecranon. This end area of the ulna, when your arm is bent, sticks out a bit, and it is also known as the 'funny bone'. When you knock it on something it really hurts! That's not really very funny at all, is it?. However, it is not the bone that you are actually hitting, it is the ulnar nerve, which runs along that part of the body. It is the largest unprotected nerve in the human body. It is being hit against the bone underneath and this causes a short sharp pain. The term elbow is in common use. If you visited a doctor and used the word elbow, he would probably know to which part of your body you were referring!

Is antebrachium proximal to the carpal region?

The hand is immediately distal to the carpal region. In particular, the metacarpals and phalanges are distal to the carpal region.

How does humerus help your body?

The function of the large head of the humerus is to allow for this great amount of movement. The humerus also provides various muscular attachment that provide for both extension and flexion of the arm. The distal end of the humerus articulates with the olecranon of the ulna and provides a very stable joint, which only allows for flexion of the arm and no extension.The humerus provides support and structure for the muscles of the upper arm.It is the connection between the scapula joint (shoulder joint) and the radius and ulna joint (elbow joint) and it supports the movement of your arm. It has insertion points for muscles, and it produces blood cells, and minerals like calcium and phosphorous from blood marrow.In terms of structure, the humerus serves as a connection between the scapula and the elbow, where it links to the two lower arm bones.The humerus bone of the upper arm (the arm in anatomy refers only to the top part of the upper limb i.e. between the elbow and the shoulder). Like all bones it gives shape to the body and acts as an attachment site for the muscles around it.Most of the muscles that actually move the humerus are within the region called the thorax or torso. The humerus joins the thorax at the glenohumeral joint (the shoulder joint) which is a synovial joint, or freely moving joint. It is actually designeda as a ball-and-socket type of joint. At this joint there are many movements that can occur: Flexion (the arm is brought up forwards so the elbow is at shoulder height), extenstion (the reverse of flexion, so the arm is pushed backwards behing the body), Abduction (the arm is lifted up and out from the side, like flapping it); adduction (the arm is lowered back into the side of the body, like unflapping it), if all four of these are combined you get circumduction (swinging your arms around in circles, forming a cone shape); rotation (when the shoulder is turned forwards or backwards).The muscles that are found on and around the humerus are mostly for acting on the forearm, i.e. at the elbow joint. This joint is a synnovial hinge joint and as such only two movements occur here: Flexion (bending the elbow) and Extension (straightening it).Their biceps brachi (or biceps) muscle is also found around the humerus but it is not really very involved in flexion of the elbow as many would believe. It is in fact used for supination of the forearm bone, the radialis, which means it turns the radius over the ulna. When they lie parallel next to each other, this is when the palm is facing forwards. Only when the forearm is fully supinated can the biceps act to flex the elbow joint. Otherwise the braachialis, a synergist to the biceps, does most of the work.The humerus is the bone of the arm. The arm in anatomy refers only to the top part of the upper limb between the elbow and the shoulder.The humerus allows you to reach, pull, lift, push and rotate objects.Humerus is the bone of arm , it connects the shoulder joint (scapula) to the elbow joint (ulna&radius) , it (with muscles) forms the main bulk of the upper arm . Humerus is a bone that is found in the arm and it help you to move your arm so you can pick stuff up.

What is the Region of lower limb attachment?

The lower limb attaches at the hip region, where the femur (thigh bone) articulates with the pelvic bone to form the hip joint.

What region of the body houses the cephalic vein?

Upper limb, forearm and arm
