How does humerus help your body?

Answer 1

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.

Answer 2

Better if the question was asked : what is the function of the humerus bone

Its a bone of the arm. Its a support. It takes part in two major joints of the arm, so it can be moved in all possible directions: the shoulder joint and the elbow joint.

Answer 3

The humerus is the bone that connects your shoulder to the elbow. So the function of the humerus is pretty much everything you do with your hands.

Answer 4

the humerus us the "funny bone" as people call it.
The humerus is the upper bone in the arm, fro the shoulder to the elbow.

It serves no protection.

Answer 5

The humerus is the bone in the upper arm. It is needed anytime you want to move your arms.

Answer 6

It helps to flex and extend the forearm and it is part of the most complex joint: the shoulder.
