The highest mean stratum thickness of 34.30 [+ or -] 1.44 was observed in the labial commissure of the group 2 experiment; this is followed by dorsum 27.20 [+ or -] 2.85 of the same group 2 experiment; the least mean stratum thickness 13.0 [+ or -] 0.17 was found in the ear pinna of group 1 experiment.
Mar 20, 2021 · Anterior refers to the ‘front’, and posterior refers to the ‘back’. Putting this in context, the heart is posterior to the sternum because it lies behind it. Equally, the sternum is anterior to the heart because it lies in front of it. Examples. Pectoralis major lies anterior to pectoralis minor. The triceps are posterior to biceps brachii.

Feb 21, 2024 · Dorsal and Ventral. “Dorsal” refers to the back or vertebral side, while “ventral” refers to the belly side. In a fish, the dorsal fin is on the back, and the belly is the ventral side. A person’s back is their dorsal surface, while the belly is the ventral surface. But, in humans, these terms more often describe relative positions ...
- Anatomical Position. To further increase precision, anatomists standardize the way in which they view the body. Just as maps are normally oriented with north at the top, the standard body “map,” or anatomical position, is that of the body standing upright, with the feet at shoulder width and parallel, toes forward.
- Regional Terms. The human body’s numerous regions have specific terms to help increase precision (see Figure 1.12). Notice that the term “brachium” or “arm” is reserved for the “upper arm” and “antebrachium” or “forearm” is used rather than “lower arm.”
- Directional Terms. Certain directional anatomical terms appear throughout this and any other anatomy textbook (Figure 1.13). These terms are essential for describing the relative locations of different body structures.
- Body Planes. A section is a two-dimensional surface of a three-dimensional structure that has been cut. Modern medical imaging devices enable clinicians to obtain “virtual sections” of living bodies.
Mar 28, 2024 · The dorsal body cavity is an enclosed internal cavity located on the posterior aspect of the body, which contains and protects the central nervous system. It is one of two major body cavities, the other being the ventral body cavity which is composed of the thoracic and abdominopelvic cavities. The dorsal body cavity is subdivided into two main ...

Jun 8, 2023 · The dorsal surface, also known as the posterior surface, refers to the back or top side of an animal or human body. It is opposite to the ventral surface, which is the front or bottom side. In anatomy, the terms "dorsal" and "posterior" are often used interchangeably, but they do have slightly different meanings. The.
