Anatomical terms of location - Relative motions

In human and zoological anatomy (sometimes called zootomy), several terms are used to describe the location of organs and other structures in the body of bilateral animals. These terms are listed and explained here. In some cases, the terminology in human anatomy may differ from that in general anatomy. The anatomical position holds more relevant information on relations and terms of location for human anatomy. Anatomical terms of location - Directions. Anatomical terms of location - Ge ...

Flexion means approximating adjacent parts of the body (usually at a joint) and extension means separating them. For example, the legs are flexed at the knee joints when sitting down, and extended when standing up. Generally, flexion produces an acute angle between adjacent parts, with its vertex at the joint, and extension produces an obtuse angle. One exception to this rule is in the ankle joint where moving the foot such that the toes move upwards is dorsiflexion and moving the ...

Structures near the midline are called medial and those near the sides of animals are called lateral. Therefore, medial structures are closer to the midsagittal plane, lateral structures are further from the midsagittal plane. Structures in the midline of the body are median. For example, your cheeks are lateral to your nose and the tip of the nose is in the median line. Ipsilateral means on the same side, contralateralSee also:

Anatomical terms of location - General usage. Animals typically have one end with a head and mouth, with the opposite end often having the anus and tail. The head end is the cranial end; the tail end is the caudal end. Within the head itself, rostral refers to the direction toward the end of the nose, and caudal is still used to refer to the tail direction. The surface or side of the body normally oriented upwards, away from the pull of gravity, is the dorsal side; the opposite ...

Anatomical terms of location - General usage. Three basic reference planes are used in zoological anatomy. The sagittal plane divides the body into left and right portions. A coronal plane divides the body into dorsal and ventral portions. A transverse plane divides the body into cranial and caudal portions. Anatomical terms of location - Usage in human anatomy. Sometimes the orientation of certain planes need to be distinguished, for instance in medical im ...
