A device that measures the dose of radiation absorbed.

A measure of the ability of the lung to diffuse gases, using carbon monoxide (CO) as a test gas, and using Ficks law for the calculations. (Carbon monoxide is used because of its remarkable ease of diffusion through the alveolar-capillary membrane and its extremely slow rate of equilibration along the pulmonary capillary.)

The percentage of each type of white blood cell present in a blood sample.

Neuron processes that conduct electrical currents toward the cell body (soma).

To deprive (an organ or body part) of a nerve supply, as by surgically removing or cutting a nerve or by blocking a nerve connection with drugs.

A tooth-like process that projects from the anterior end of the centrum of the axis in the spinal column, serves as a pivot on which the atlas rotates, and is morphologically the centrum of the atlas though detached from that vertebra and more or less perfectly united with the next one behind — called also odontoid process.

A term applied to the collapse of individual alveoli sacs such that they are not able to exchange gases. After collapse, reopening is difficult. Repeated episodes can cause injury and/or sustained regional collapse. Keeping the circuit closed during suctioning and other activities, delivers constant pressure (PEEP) to maintain alveolar patency optimizing oxygen saturation levels, minimizing trauma and preventing atelectasis.

A general term referring to any inflammation of the skin; may be caused by an irritation or Type IV, delayed type hypersensitivity.

A segmental area of skin and subcutaneous tissue innervated by branches of a specific spinal nerve. For example, the area of skin supplied with afferent nerve fibers by a single posterior spinal root.

A skin incision.
