Lecture on Anatomy and Medical Imaging

Flashcards created to assist with understanding key vocabulary and concepts related to anatomy and medical imaging.

Anatomy

The study of the structure of the body and its organs.

Cellular Level

The most basic level of biological organization, consisting of individual cells.

Tissue Level

The level of organization in which groups of similar cells work together to perform specific functions.

Gross Anatomy

The study of the body's structures that can be seen with the naked eye.

Regional Approach

An approach to anatomy that divides the body into regions and examines each region separately.

Systemic Approach

An approach to anatomy that studies the body's systems individually.

Surface Anatomy

The study of external features of the body that can provide information about underlying structures.

Embryology

The study of the development of an organism from fertilization up to eight weeks.

Pathology

The study of diseases and how they affect the structure and function of the body's organs.

Cross Sectional Anatomy

The study of anatomy using imaging techniques to visualize cross sections of the body.

Functional Morphology

The study of the relationship between the structure of a body part and its function.

Comparative Anatomy

The study of similarities and differences in the anatomy of different species.

Medical Imaging

Techniques used to visualize the inside of the body without surgery.

X-ray

A form of medical imaging that uses radiation to visualize internal structures.

CT Scan

Computed Tomography; uses rotating X-rays to create cross-sectional images of the body.

Angiogram

An imaging technique used to visualize blood vessels after injecting a contrast medium.

PET Scan

Positron Emission Tomography; a nuclear medicine imaging technique used to observe metabolic processes.

Ultrasound

An imaging technique that uses high-frequency sound waves to produce images of structures within the body.

MRI

Magnetic Resonance Imaging; an imaging technique that uses strong magnets and radio waves to visualize internal structures.

Anatomical Position

A standardized position used as a reference in anatomy, where the body is standing upright, facing forward, with arms at the sides and palms facing forward.

Dorsal Cavity

The posterior body cavity that houses the brain and spinal cord.

Ventral Cavity

The anterior body cavity that houses organs in the thoracic and abdominal regions.

Bilateral Symmetry

A characteristic of organisms where the left and right sides are mirror images.

Pharyngeal Arches

Embryonic structures that develop into various head and neck features.

Mammals

A class of vertebrates characterized by mammary glands, hair, and three middle ear bones.

Primates

The highest rank of mammals, characterized by large brains and advanced cognitive abilities.

Thoracic Region

The part of the body that contains the chest, including the heart and lungs.

Abdominal Region

The area of the body that contains the digestive organs.

Pelvic Region

The lower part of the torso that contains the reproductive and some digestive organs.
