- Human anatomy : study of the structure of the human

body and the relationship of its constituent parts to each

other.

- Histology : study of tissues [including the cells] by means

of a microscope.

- Neuroanatomy : study of the nervous system, both by

gross anatomy and microscopically.

Introduction to Anatomy

TermsDefinitionAnatomicalposition

the person is standing erect, with the

upper limbs by his sides and the face

and palms of the hands are directed

forward.

Median sagittal plane

It is a vertical plane passing through the

center of the body, dividing it into 2

equal halves right and left.

Para median plane

Any plane that lies parallel to the

median plane on the right or left sides.

TermsDefinition

Coronal planes:vertical planes at right angles to the median plane.

Horizontal (transverse) planes

at right angles to both the median and coronal planes.

Terms Meaning Median on the midline.

Medial nearer to the median plane.

Lateralaway from the median plane.

Anteriornear to the front of the body.

Posteriornear to the back of the body.

Proximal

Distal

Terms Meaning Proximal near to the root of

the limb.

DistalFar away from the

root of the limb.

Superficial

near to the surface of the body.

Deepfar away from the surface of the body.

Superior near to the upper

end of the body.

Inferior far away from the upper end of the body.

Terms of movements

Joint: the site where 2 or more

bones meet.Movements in the sagittal plane:

1.Flexion: usually approximating

two anterior surfaces together but

sometimes two posterior surfaces

as in the knee joint.

2. Extension: straightening the joint

and usually takes place in a

posterior direction.

Movements in the coronal plane:1. Lateral flexion: movement of the

trunk or the head in the coronal plane.

2. Abduction: movement of the limb away from the midline of the body.

3. Adduction: movement of the limb toward the body.

In the hand: Abduction and adduction of fingers are

movements away from and toward the middle finger (the axis).

In the foot: Abduction and adduction of fingers are

movements away from and toward the second toe (the axis).

Terms Definitions Rotationmovement of a part of the body

around its long axis.

Medial rotationanterior surface of the part faces medially.

Lateral rotationanterior surface the part faces laterally

Pronation of the forearm

medial rotation of the forearm where the palm of hand faces posteriorly.

Supination of the forearm

the lateral rotation of the forearm where the palm of hand faces anteriorly.

Terms Definition

Circumduction

combination of flexion, abduction,

extension, and adduction in

sequence.

Protraction forward movement

Retraction Backward movement

Inversion movement of the foot so that the sole faces medially.

Eversion movement of the foot so that the

sole faces laterally.

Movements of the thumbTerms Definition

Flexion movement of the thumb medially across the palm in the coronal plane.

Extension movement of the thumb laterally away from the palm in the coronal plane.

Abduction movement of the thumb anteriorly away form the palm in the sagittal plane.

Adduction movement of the thumb posteriorly toward the palm in the sagittal plane
