Farther down below the surface Planes of Sectioning We will spend time studying not only the surface anatomy of many organs, but we will also have to look at the interior anatomy of many organs.
Many structures vary slightly between people, for example muscles that attach in slightly different places.
This figure shows the human body with the major muscle groups labeled. For example, the skin is superficial to the bones, and the brain is deep to the skull. The upper right square is the right hypochondriac region and contains the base of the right ribs.
Cranial and caudalwhich describe structures close to the top of the skull cranialand towards the bottom of the body caudal. The insertion is on the bone deemed to move towards the origin during muscle contraction. The frontal plane is often referred to as a coronal plane, following Latin corona, which means "crown".
The thoracic cavity is open at the top and the abdominal cavity is open at the bottom. Caudal — at or near the tail or posterior end of the body. Breathing is the main way the shape of these two cavities changes.
For example, blood can be said to flow in a proximal or distal direction, and anteroposterior, mediolateral, and inferosuperior axes are lines along which the body extends, like the X, Y, and Z axes of a Cartesian coordinate system.
This is anatomy, so we give a name to each surface of the pericardium. Visceral — may be used instead of deep. The abdominal cavity changes shape similar to a water-filled balloon. Lateral Away from the body's longitudinal axis; away from the midsagittal plane the thigh articulates with the lateral surface of the pelvis; moving laterally from the nose brings you to the cheeks.
The insertion is on the bone deemed to move towards the origin during muscle contraction. Intermediate — means between—your heart is intermediate to your lungs. Both cavities are bound on the back by the spine.
Medial and lateralwhich describe a position that is closer to medial or further from lateral the midline of the body. Each movement at a synovial joint results from the contraction or relaxation of the muscles that are attached to the bones on either side of the articulation. One particularly important aspect of gross anatomy of muscles is pennation or lack thereof.
Superficial and deepwhich describe structures that are closer to superficial or further from deep the surface of the body. The Major Anatomical Regions, Directions and Cavities of the Human Body The Major Anatomical Regions, Directions and Cavities of the Human Body Many terms are used to describe the human body and its various positions when being observed, studied or referred to in any medical discussion.
Here’s a look at all of the major regions (from the outside of the body) and how they relate to each other in the anatomical position highlighted in the preceding section: The cephalic region (head) or cranial region (skull) is at the top of the body and visible from the front and rear.
Anatomical directional terms are like the directions on a compass rose of a map. Like the directions, North, South, East and West, they can be used to describe the locations of structures in relation to other structures or locations in the body.
All directional terms reference position with regards to anatomical position even if the body in question is in a different position.

Like the directions, North, South, East and West, they can be used to describe the locations of structures in relation to other structures or locations in the body.

The dorsal cavity is the space within the skull and the spinal canal.
The spinal canal is surrounded by the vertebrae. The cranial cavity is the fluid filled space inside the cranium.Major anatomical regions landmarks directions and cavities
