Long head, with its synovial sheath
The tricpes brachii muscle is one muscle. It is an extensor muscle, meaning that it opens, or extends the arm from the shoulder (as opposed to the bicpes, which is a flexor muscle, that closes the arm.)
well the muscles sued are your tricep and bicep they conteract and relax ............................................................................................................................................. These muscles would be used along a sequence of muscle innervation. The first muscles would be the pectoralis major and the torso, then travelling along the biceps brachii, then along the extensor and flexor muscles running along the radial & ulna bones and then finally into the intricate muscles in the hands.
Biceps flex the arm at the elbow, and triceps (along with the brachialis) extend it. The deltoids raise the arms.
In human anatomy, the cephalic vein (or antecubital vein[dubious - discuss]) is a superficial vein of the upper limb.It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle.Superiorly the cephalic vein passes between the deltoid and pectoralis major muscles (deltopectoral groove) and through thedeltopectoral triangle, where it empties into the axillary vein.The cephalic vein is often visible through the skin, and its location in the deltopectoral groove is fairly consistent, making this site a good candidate for venous access. Permanent pacemaker leads are often placed in the cephalic vein in the deltopectoral groove. The vein may be used for intravenous access, and is sometimes referred to as the 'House-man's Friend' because a large bore cannula may be easily placed.[citation needed]
a pulley is a wheel with a groove along with a rope or chain.
wheel, sheave, or drum which turnes an axle or rod. It also has a groove or path along its outside. A rope, chain, or cable slides through the groove.
The woodworking form "tongue and groove" (also tongue-in-groove) connects separate strips of wood, such as flooring, by having a milled extruding projection or ridge (tongue) on one side, that perfectly matches and fits into a milled concave recessed slot (groove) along the side of the adjacent board.
Biceps and Lats primarily, along with a lot of support from the forearm and shoulder muscles.
The Ambulacral Groove
pectoralis minor along with serratus anterior to reach down to pick up the phone; brachialis, biceps brachii, and brachioradialis muscles to flex the forearm; adductor pollicis draws thumb to the palm, and flexor digitorum superficialis flexes fingers to grab the telephone; deltoid, to anteriorly flex and swing your arm at glenohumeral joint (shoulder) to bring the phone to your ear level.
I think you are talking about a groove cast. Groove casts form in the bottom of a stream when transported sediment is dragged along a mud bottom.
the answer to your question is easy the simple machine a wagon wheel is a wheel and axel
