Intro to Anatomy

Anatomy

The study of internal and external structures of the body and their relationships.

Microscopic Anatomy

The study of structures that require magnification to be seen.

Cytology

The study of cells.

Histology

The study of tissues.

Gross Anatomy

The study of structures visible to the naked eye. Larger structures that make up the body both internally and externally

Surface Anatomy

The general anatomical form visible on the surface of the body.

Surface Anatomy Examples

things that are visible and often palpable like spine on back

Regional Anatomy

The study of structures located in specific body regions.

Regional Anatomy example

the head is a region despite it have multiple different systems in it

Systemic Anatomy

The study of the organ systems of the body.

Levels of Organization

Chemical/molecular, cellular, tissue, organ, organ system, organism

Chemical/Molecular level

four elements make up 99% of the body

there are major classes of molecules

Types of tissue

muscular, neural, connective, and epithelial

Homeostasis

The maintenance of a relatively constant internal environment for survival.

Disease

A failure of the body to maintain homeostasis.

Pathology

The study of disease.

Anatomical Landmarks

Prominent structures that are usually palpable or visible.

Superficial anatomy

things that are noticable when just looking at a person

What can superfitell you?

based on a person’s skin, walk, posture, movement it can indicate a person’s health

Anatomical Position

A standard position where the person stands with feet flat and palms facing forward.

Supine

Laying flat on the back.

Prone

Laying face down.

Superior (Cranial)

Towards the top of the head.

Inferior (Caudal)

Towards the feet.

Anterior (Ventral)

Towards the front of the body.

Posterior (Dorsal)

Towards the back of the body.

Medial

Closer to the midline of the body.

Lateral

Towards the side of the body.

Superficial

Closer to the surface of the body.

Deep

Further inside the body.

Proximal

Closer to the attachment point of a limb to the body.

Distal

Further from the attachment point of a limb to the body.

Sagittal Plane

A vertical plane that divides the body into left and right sections.

Midsagittal Plane

A sagittal plane that runs down the midline of the body.

Parasagittal Plane

A sagittal plane that runs off-centered.

Transverse Plane

A horizontal plane that divides the body into superior and inferior sections.

Frontal (Coronal) Plane

A plane that divides the body into anterior and posterior sections.

Oblique Plane

A diagonal plane that cuts through the body.
