Major anatomical regions landmarks directions and cavities

Because of how these two cavities are linked together in shape change, you can see that the quality of breathing affects the health of abdominal Major anatomical regions landmarks directions and cavities and the health of our organs affects the quality of our breathing.

The insertion is on the bone deemed to move towards the origin during muscle contraction.

Joint Movement is not limited to only synovial joints, although they allow for most freedom. The brachioradialisin the forearm, and brachialislocated deep to the biceps in the upper arm, are both synergists that aid in this motion. The foot is inferior below to the knee. 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.

It is lined with a membrane and contains the stomach, lower part of the esophagus, small and large intestines except sigmoid and rectumspleen, liver, gallbladder, pancreas, adrenal glands, kidneys and ureters.

Anatomical Planes & Body Cavities Quiz

Superior means above, inferior means below. Something that is patent may also refer to a channel such as a blood vesselsection of bowelcollecting system or duct that is not occluded and remains open to free flow. For example, if a person makes a "thumbs up" gesture, supination will cause the thumb to point away from the body midline and the fingers and plam to be upwards, while pronation will cause the thumb to point towards the body midline with the back of the hand upwards.

If it divides the body into unequal right and left sides, it is called a parasagittal plane, or less commonly a longitudinal section. For example, the presence or absence of the palmaris longus tendon.

Three planes are commonly referred to in anatomy and medicine: In the fingers of the hand, a proximal joint is closest to the wrist and a distal joint is farthest from the wrist. The abdominal cavity is between the diaphragm and the pelvis.

Anatomy Terms

Proximal and distal are often used when describing arms and legs. If this vertical plane runs directly down the middle of the body, it is called the midsagittal or median plane.

Anatomical terminology

Ventral and dorsalwhich describe structures derived from the front ventral and back dorsal of the embryobefore limb rotation.

There are also terms that describe specific body parts. Ventral Cavity The ventral cavity is on the front of the trunk.

Directional Terms In general, directional terms are grouped in pairs of opposites based on the standard anatomical position. The regions are named below and the corresponding regions are labeled Between the parietal and visceral layers is a very thin, fluid-filled serous space, or cavity.

Caudal — at or near the tail or posterior end of the body. This figure shows the human body with the major muscle groups labeled. Paired, referring to a structure that is present on both sides of the body. The ventral cavity is on the front anterior of the body and is divided into the thoracic cavity chest and abdominopelvic cavity.

Medial and lateralwhich describe a position that is closer to medial or further from lateral the midline of the body. Visceral — may be used instead of deep. For example, the Lotus position posture in yoga requires the legs to be externally rotated.

The more you eat and drink, the harder it is for the diaphragm to compress the abdominal cavity—which is why it is harder to breathe after a large meal.

Left Upper Quadrant LUQ — Left lobe of liver, stomach, small intestine, transverse colonsplenic flexure, pancreas, left kidney and spleen. Contains parts of the sigmoid colon, the urinary bladder and ureters, the uterus and ovaries womenand portions of the small intestines.

The vertical; or midclavicular lines, are drawn as if dropped from the midpoint of each clavicle. A plexus refers to a net-like arrangement of a nerve. Muscles are often present that engage in several actions of the joint; able to perform for example both flexion and extension of the forearm as in the biceps and triceps respectively.

For example, a star jump requires the legs to be abducted. The most widely used terms are those that describe the 9 abdominal regions shown in the image to the right. The body reference planes are used to locate or describe the location of structures in the body. Pronation and supination refer to rotation of the forearm or foot so that in the anatomical position the palm or sole is facing anteriorly supination or posteriorly pronation.

For example, the hands are paired structures. For example, the skin is superficial to the bones, and the brain is deep to the skull. Additionally, synovial joints can be divided into different types, depending on their axis of movement.BIO LAB 1.
