Where is the humurus?
The humerus is the top of your arm. Where you biceps are is where your humerus.
Is groove of the humerus is origin of biceps muscle?
yes
What is the medical term meaning a fracture in the middle third of the humerus?
A fracture in the second third of the humerus. Humerus being the bone that your biceps lies on.
What muscle has an attachment on the superior facet of greater tubercle of humerus?
Biceps
How do the tricep bicep and humerus work?
The Biceps contract when the triceps relax and the biceps relax when the triceps contact!! The humerus are a bone therefore it just makes the arm supported... (if you want to add anything to this just do it!!!)
Where is the humerus in relationship to the elbow?
Above it (it's under the biceps).The humerus is proximal to the elbow.
What muscle flexes the humerus?
The humerus doesnt flex. bones dont flex. but the muscles on top are called biceps.
Does the biceps brachii muscle originate or insert on the humerus?
It inserts onto the humerus. It originates from the coracoid process of the scapula. There are 2 parts - Long head and short head. The long head is connected to the coracoid process by a tendon that comes up between the tubercules of the humerous. The short head is connected directly to the humerus.
Where are the triceps based?
Under your biceps, under the humerus (the bone between your elbow and your shoulder)
What muscle flexes the elbow but neither originates nor inserts on the humerus?
The biceps brachii muscle.
Name a muscle that is a synergistic to the biceps brachii during elbow flexing?
Brachialis - attaches from the anterior proximal humerus to the coronoid process of the ulna - strong flexor of the elbowBrachioradialis - attaches from the lateral supracondylar ridge of the humerus to the distal styloid of the radius - weak flexor of the elbow
What movement would be produced if the biceps contracted if the elbow was held in extension?
The interesting thing about the Biceps Humerous (Bicep=Two Heads Humerus=Attached to the humerus bone) is that its main function is NOT to flex the elbow joint. This is moslty done by Brachialis muscle although the Biceps does help. The main action of the biceps, and also what is does if it is not flexing the elbo is to Suppinate the Forearm. This means to turn the palm from facing backwards to facing forwards. In fact the biceps cannot flex the elbow unledd the forearm has first been supinated.
