2024年9月7日 · Medial and Lateral. Imagine a line in the sagittal plane, splitting the right and left halves evenly. This is the midline. Medial means towards the midline, lateral means away from the midline. Examples: The eye is lateral to the nose. The nose is medial to the ears. The brachial artery lies medial to the biceps tendon.

The hand needs to be mobile in order to position the fingers and thumb. Adequate strength forms the basis for normal hand function. The hand also must be coordinated to perform fine motor tasks with precision. The structures that form and move the hand require proper alignment and control in order for normal hand function to occur.

Medial means toward the midline of the body. It’s easy to remember because medial sounds like “middle.” Lateral means away from the body’s midline. It’s easy to remember because a popular exercise for the shoulders is lateral raises, in which you raise your arms away from the body’s midline. Intermediate means “between” two ...

Lateral (from Latin lateralis 'to the side') describes something to the sides of an animal, as in "left lateral" and "right lateral". Medial (from Latin medius 'middle') describes structures close to the midline, [2] or closer to the midline than another structure. For example, in a human, the arms are lateral to the torso. The genitals are ...

2010年8月14日 · Each finger has three main segments: The two terms distal and proximal mean “towards the tip” and “towards the body”, respectively. You can apply this terminology to other parts of the body, like the foot (the toes are distal to the ankle, or the knee is proximal to the toenail). The thumb has only two segments:

Any muscle that moves the fingers or toes. Pronate = Medial rotation of the hand from anatomical position. Quadracepts Lumbrum (L quadra = "four" + L. caput/ Gk. cephalos = "head" + lumbar). A 4-sided muscle in the lumbar region. Rectus = "straight". Rectus femoris and rectus abdominus are straight muscles of the thigh and abdomen.

Medial is part closer to trunk in the anatomical position (ulna of hand). The patient sits at the end of the table. Place the palmar surface of hand in contact with cassette/image receptor. Fingers slightly separated and fingers as flat as possible. Elbow in …

This article discusses the key anatomical structures of the hand that enable functional movements, including the bony structures, articulations, ligaments, muscles, nerves and the vascular supply.

From an anterior view of the wrist in anatomical position, the eight carpal bones are easily identifiable. The proximal row of four carpal bones listed from lateral to medial are the Scaphoid, Lunate, Triquetrum, and Pisiform. The distal row of carpal bones listed from lateral to medial are the Trapezium, Trapezoid, Capitate, and Hamate.

Proximal row (medial to lateral): scaphoid, lunate, triquetrum, and pisiform. Distal row (medial to lateral): trapezium, trapezoid, capitate, and hamate. Intercarpal synovial joints exist between the carpal bones. B. The proximal row of carpal bones articulates with the distal end of the radius, forming the wrist joint (radiocarpal joint). C.
