How to Describe the Pectoral Using Anatomical Terms

The human body is shown in anatomical position in an a anterior view and a b posterior view. The patella is located anteriorly in the lower limb.

The body is divided into two major portions.

. Directional Terms in Human Anatomy. The upper limbs are held out to each side and the palms of the hands face forward as illustrated in Figure 141. Toward the bottom toward the belly.

For instance an anatomist might describe. The palms are facing forward with the fingers extended and the thumbs are pointing away from the body. Pelvis is inferior to the chest.

The anatomical position is a standing position with the head facing forward and the arms to the side. The axial body runs right down the center axis and consists of everything except the limbs meaning the head neck thorax chest and back abdomen and pelvis. The epidermis is the outermost layer that provides.

Anatomical Directional Terms. Anatomical terms of movement are used to describe the actions of muscles upon the skeleton. Using anatomical terminology this is expressed as the heart is medial to the arms.

Near closer to the origin. Cephalic region contains thefrontalforehead orbitaleye buccal cheek nasalnose oral mouth and occipitalback of the head regions. The sternum is anterior to the heart.

The dorsal surface of the penis is actually the anterior front-facing surface in the flaccid state. The umbilicus is inferior to the sternum. Anatomy The branch of biology that studies the structures of organisms bodies.

Many anatomical terms can be combined either to indicate a position in two axes simultaneously or to indicate the direction of a movement relative to the body. Certain directional anatomical terms appear throughout this and any other anatomy textbook Figure 113. The term anterior would be used even if the hand were palm down on a table.

The anatomical regions shown compartmentalize the human body. This diagram shows the three anatomical planes of the body. A particular body part is farther from the trunk or farther from another specified point of reference than another part.

Using this standard position reduces confusion. The regions of the body are labeled in boldface. Spine is on the dorsal side of our body.

Superior means higher inferior means lower. In front of front. The terms used assume that the body begins in the anatomical position.

Below is a list of the other surface anatomy terms that are within the main body regions. Regions of the Human Body. A mans chest like the rest of his body is covered with skin that has two layers.

Thoracic region contains mammaryor pectoral cheststernal andaxillaryarmpit regions. Anatomical terms can be combined to more precisely describe the location of an organ or a region. The vertebral column is dorsal to the aorta.

Pectoralis major lies anterior to pectoralis minor. The forebrain is rostral to the brainstem. Directional Term Origin Meaning Example.

The esophagus is posterior to the trachea. Anatomical plane A conceptual plane that is used to divide the body into sections in order to make it easier to discuss anatomy. The triceps are posterior to biceps brachii.

Away from farther from the origin. For example a scar in the anterior front carpal wrist. Describe how an early interest in the human body eventually led to the development of modern medical science.

Certain directional anatomical terms appear throughout this and any other anatomy textbook Figure 113. Superior and Inferior These terms refer to the vertical axis. To clearly explain exactly the relation of a body structure to each other directional terms are used.

A part that is closer to the trunk of the body or closer to another specified point of reference than another point. A plane that separates the body or structure into anterior and posterior sections Sagittal A plane separating the body or a structure into left and right sections A midsagittal plane seperates into equal left and right halves Transverse or Horizontal A plane that separates the body or structure into superior and inferior sections. In men the penis is considered to be erect in the anatomical position eg.

Just like on a map a region refers to a certain area. These terms are essential for describing the. Near the upper surface toward the back.

You will be able to describe the bodys regions using the terms from the figure. Muscles contract to produce movement at joints and the subsequent movements can be precisely described using this terminology. Abdomen is on the ventral side of our body.

Early doctors began to learn how certain herbs and potions affected bod functions and the idea that humans could understand forces that caused natural events led to the development of modern science. This indicates that the right chest muscle is both anterior and lateral to the breast bone. The cephalic end of the embryonic neural tube develops into the brain.

These terms are essential for describing the relative locations of different body structures. The feet are spaced slightly apart with the toes pointing forward. It does not matter how the body being described is oriented the terms are used as if it is in anatomical position.

For example anterolateral indicates a position that is both anterior and lateral to the body axis such as the bulk of the pectoralis major muscle. The aorta is ventral to the vertebral column. For example one might say that the right chest muscle also called the pectoralis major is anterolateral to the breastbone also known as the sternum.

Ultimately communicating using anatomical terms makes it easy to communicate description of body areas regardless of the individuals position. Quadruped An animal that walks on four legs. Head is superior to the chest.

After behind following toward the rear. The head is superior to the neck. For example to describe the relationship or location of the heart to the arms we can say the heart is located in between the arms.

You will be able to describe the bodys regions using the terms from the figure. Most movements have an opposite movement also known. A body that is lying down is described as either prone or supine.
