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.
When explaining lateral and medial positions, the body is typically in an anatomical position, standing upright with palms facing forward and feet parallel. Lateral refers to a position further away from the midline of the body, while medial refers to a position closer to the midline.

Which body plane creates the directional terms medial and lateral?
The terms medial and lateral are evaluated along the coronal plane. When drawing an imaginary line to evaluate a structure's position in terms of medial and lateral, the line drawn is parallel to the sagittal plane.
The anatomical position is not necessary to know which way is lateral vs medial in the body?
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.
Four proximal carpal bones from lateral to medial?
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.
Are the thoracic vertebrae medial or lateral to the scapula?
You can describe them as medial to the scapula.
Is the ribcage medial to the right arm?
Yes, the ribcage is medial to the right arm. The term "medial" refers to a position closer to the midline of the body, while the right arm is more lateral or further away from the midline.
What is the opposite of medial?
The opposite of medial is lateral. Medial refers to a location closer to the midline of the body, while lateral refers to a position further away from the midline.
Which body plane creates the directional terms medial and lateral?
The terms medial and lateral are evaluated along the coronal plane. When drawing an imaginary line to evaluate a structure's position in terms of medial and lateral, the line drawn is parallel to the sagittal plane.
Is the ear medial or lateral to the eye?
The ears are lateral to the eyes. The eyes are medial to the ears.
Is the ulna medial or lateral compared to the radius?
Correct. It is also proximally medial to the radius in pronation, however at its distal end it is lateral.
Is the elbow medial to the wrist?
The elbow is proximal to the wrist. In anatomical position, it is neither medial nor lateral to the wrist.
Compare and contrast the directions lateral and medial on the human body?
"Lateral" refers to the direction away from the midline of the body, while "medial" refers to the direction toward the midline. In simpler terms, lateral means toward the sides of the body, while medial means toward the center or midline of the body.
The anatomical position is not necessary to know which way is lateral vs medial in the body?
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.
Four proximal carpal bones from lateral to medial?
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.
Which is medial the pollux or the 5th metacarpal?
The pollux, or thumb, is lateral to the fifth metacarpal in anatomical position. The pinkie is medial to the thumb.
What is the position of lateral?
"Lying on your side." Lateral means pertaining to the side of your body, and medial means pertaining to the middle of your body.
Are the thoracic vertebrae medial or lateral to the scapula?
You can describe them as medial to the scapula.
Is the ribcage medial to the right arm?
Yes, the ribcage is medial to the right arm. The term "medial" refers to a position closer to the midline of the body, while the right arm is more lateral or further away from the midline.
