The terms proximal (from Latin proximus 'nearest') and distal (from Latin distare 'to stand away from') are used to describe parts of a feature that are close to or distant from the main mass of the body, respectively. [29] Thus the upper arm in humans is proximal and the hand is distal.
The rostro-caudal axis of the human central nervous system (magenta in the diagram) makes a near 90° bend at the level of the midbrain and continues through the brain-stem and spinal cord. In human anatomy, the occipital lobes and the back of the head are posterior but not caudal to the frontal lobes and the face.
Rostral and caudal, which describe structures close to (rostral) or farther from (caudal) the nose. For example, the eyes are rostral to the back of the skull, and the tailbone is caudal to the chest. Cranial and caudal, which describe structures close to the top of the skull (cranial), and towards the bottom of the body (caudal).
BMI stands for body mass index. It’s a calculation of your height relatively to your weight, according to the Centers for Disease Control and Prevention (CDC). BMI is generally classified into ...
Extensor indicis (index finger only) of phalanges, at interphalangeal joints [4] Lumbricals of the hand; Dorsal interossei of the hand; Palmar interossei; of thumb [5] Extensor pollicis brevis (proximal phalange) Extensor pollicis longus (distal phalange)
Caudal (anatomical term) (from Latin cauda; tail), used to describe how close something is to the trailing end of an organism; Caudal artery, the portion of the dorsal aorta of a vertebrate that passes into the tail; Caudal cell mass, the aggregate of undifferentiated cells at the caudal end on the spine; Caudal fin, the tail fin of a fish
An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and non-human anatomy, three principal planes are used:
In humans and other mammals, the caudal cell mass (also tail bud or caudal eminence in humans) is the aggregate of undifferentiated cells at the caudal end on the spine.The caudal end of the spinal cord first begins to form after primary neurulation has taken place, indicating that it develops after the cranial portion of the spinal cord has developed.
