Orientation of the body
Terms in this set (104)
The study of the structure and shape of the bodyy and its parts
The study of how the body and its oarts work or function
Median or Midsaggital
The midline longitudinal plane dividing the head and torso into right and left halves
A longitudinal plane dividing the body into right and left parts. It is parallel to the median plane.
Frontal or Coronal
A longitudinal plane dividing the body into front and back halves or parts.
Transverse, Horizontal, or Cross section
Divides the body into upper and lower halves or parts. It is perpendicular to the longitudinal planes.
The upper (nose through larynx) and lower respiratory track (trachea through the air spaces of lungs).
Concerned with the breakdown, digestion, and Assimilation of foods as well as excreation.
Consevation of water and maintance of acid-base balance. Kidneys are the main function of system.
Immune/ lymphoid system
Organs concerned i
With body diffense, a dicise arrangement of immune related cells, concerned with resistance to invasive microorganisms and removal of damaged or abnormal cells.
Concerned with the excreation if sex hormones.
Tiny building blocks of matter, combine to form molecules.
The smallest unit of all living things.
Consists of groups of similar cells that have a common function.
A structure composed of two or more tissue types that preform a specific function for the body.
A group of organs that work together to accomplish a common purpose.
Represents the highest level of structural organization.
The external covering of the body. Waterproofs the body and cushions and protects the deeper tissues from injury.
Consists of bones, cartilages, ligaments, and joints. Supports the body and provides framework that the skeletal muscles use to cause movement.
The muscles of the body have one function- to contract, or shorten.
The body's fast acting control system. It consists of the brain, spinal cord, nerves, and sensory receptors.
Controls body activities, but it acts much more slowly.
Carries oxygen, nutrients, hormones, and other substances to and from the tissue cells where exchanges are made.
Complements cardiovascular system. Return leaked fluid from the blood back to the blood vessels so that blood can be kept continuously circulating through the body.
Includes all activities promoted be the muscular system, such as propelling ourselves from one place to another.
The ability to sense changes in the environment and then to react to them.
Process of breaking down ingested food into simple molecules that can then be absorbed into the blood.
All chemical reactions that occur within the body cells.
The process of removing waste from the body.
The production of off spring, can occur on the cellular or organismal level.
The body's ability to maintain relatively stable internal conditions even though the outside world is continuously chaining.
Some type of sensor that monitors and responds to changes in the environment.
Determines the level at which a variable is to be maintained, analyze the information it receives and then determines the appropriate response or course of infection.
Provides the means for the control centers response to the stimulus.
Negative Feedback Mechanisms
The net effect of the response to the stimulus is to shut off the original stimulus or reduce its intensity.
Positive Feedback Mechanisms
Tend to increase the original disturbance and to push the variable farther from its original value.
Allow medical personnel and anatomists to explain exactly where one body structure is in relation to another.
Superior, Cranial, or Cephalic
Toward the head end or upper part of a structure or the body, above.
away from the head end or toward the lower part of a structure or the body, below.
Toward or at the front of the body, front.
Toward or at the backside of the body, behind.
Toward or at the midline of the body, on the inner side of.
Away from the midline of the body, on the outer side of.
Close to the origin of the body part or point of attachment of a limb to the body trunk.
Farther from the origin of a body part or the point of attachment of a limb to the body trunk.
Toward or at the body surface.
Away from the body surface; more internal.
Anterior body trunk inferior to ribs.
Point of shoulder.
Anterior surface of elbow.
Curve of shoulder formed by large deltoid muscle.
Lateral part of leg.
Area where thigh meets body trunk, groin.
Area overlying the pelvis anteriorly.
Heel of foot.
Area of back between ribs and hips.
Posterior surface of head.
Posterior surface of elbow.
Posterior knee area.
Area between hips.
Shoulder blade region.
The posterior surface of lower leg; the calf.
Area of spine.
The sole of the foot.
The space inside the bony skull.
Extends from the cranial cavity nearly to the end of the vertebral column.
Separated from the rest of the ventral cavity by a dome shaped muscle.
Separates the thoracic cavity and the ventral cavity.
Separates the lungs into right and left cavities in the thoracic cavity.
Subdivide it into a superior abdominal cavity and inferior pelvic cavity.
Containing the stomach, liver, intestines, and other organs.
With the reproductive organs, bladder, and rectum.
The centermost region, deep to and surrounding the umbilicus.
Located superior to the umbilical region
Is inferior to the umbilical region.
Right and Left Iliac or Inguinal Region
Are lateral to the hypogastric region.
Right and Left Lumbar Region
Lie lateral to the umbilical region.
Right and Left Hypochondriac Region
Flank the epigastric region and contain the lower ribs.
Commonly called the mouth, contains teeth and tongue.
Located within and posterior to the nose, the nasal cavity is part of the respiratory system passageways.
The skull house the eyes and present them in anterior position.
Middle Ear Cavity
carved into the skull lie just medial to the eardrums. These cavities contain tiny bones that transmit sound vibrations to the hearing receptors in the inner ear.
