Its C:
Away from the midline of the body or body part.
The ears are lateral to the eyes. The eyes are medial to the ears.
Medial and lateral are terms used to describe the relative position of body parts. Medial refers to being closer to the midline of the body, while lateral means being farther away from the midline.
In the anatomical position of the hand the palm faces to anterior side. Because you use your palm as you flex it. You do not use the dorsal aspect of the hand normally. So in the anatomical position the palm faces on the anterior side. That way the thumb comes on lateral side to the fingers.
The humerus is lateral to the sternum. The sternum, or breastbone, is midline.
The anatomical position of the radius bone (forearm bone) in relation to the ulna bone is due to the positioning of the thumb in the human hand. The radius is located lateral (on the same side as the thumb) to the ulna bone when the palms are facing up. This positioning allows for rotation of the forearm and greater range of motion in activities like grasping and rotating objects.
It is important to understand the anatomical position to accurately identify lateral and medial directions in the body. In the anatomical position, the body is upright, facing forward, with palms facing forward. Lateral refers to structures that are further away from the midline, while medial refers to structures closer to the midline.
The elbow is proximal to the wrist. In anatomical position, it is neither medial nor lateral to the wrist.
Correct. It is also proximally medial to the radius in pronation, however at its distal end it is lateral.
The pollux, or thumb, is lateral to the fifth metacarpal in anatomical position. The pinkie is medial to the thumb.
The ears are lateral to the eyes. The eyes are medial to the ears.
Medial and lateral are terms used to describe the relative position of body parts. Medial refers to being closer to the midline of the body, while lateral means being farther away from the midline.
The radius forms the bump on the lateral side of the wrist. The ulna forms the bump on the medial side of the wrist. Remember to keep anatomical position in mind when determining directionals for the upper limb.
The four proximal carpal bones from lateral to medial are the scaphoid, lunate, triquetrum, and pisiform. Remember what anatomical position looks like when thinking about the lateral or medial location of the bones of the upper extremity.
In the anatomical position of the hand the palm faces to anterior side. Because you use your palm as you flex it. You do not use the dorsal aspect of the hand normally. So in the anatomical position the palm faces on the anterior side. That way the thumb comes on lateral side to the fingers.
The humerus is lateral to the sternum. The sternum, or breastbone, is midline.
Any explanation always starts with the body in anatomical position. The hands/forearms are supine (palm facing up like you're holding a cup of soup). This would make the pinky (and ulnar bone) medial with the thumb (and radius bone) lateral. At the elbow joint there is a lateral and medial epicondyle (a projection of the humerus where the forearm extensor and flexor muscles attach respectively). For lateral and medial positions this only really affects the forearm/hand since everything else is straightforward.
The anatomical position of the radius bone (forearm bone) in relation to the ulna bone is due to the positioning of the thumb in the human hand. The radius is located lateral (on the same side as the thumb) to the ulna bone when the palms are facing up. This positioning allows for rotation of the forearm and greater range of motion in activities like grasping and rotating objects.
