Introduction
-
Definition human anatomy is the science which deals with structures and functions of the human body, and it is the basic course of medicine aims

(1) locomotor system (2) alimentary system (3) respiratory system (4) urinary system (5) genital system (6) endocrine system (7) circulatory system(angiology) (8) nervous system (9) sense organs
There are nine systems in the human body:
-
Anatomical position
-
superior , inferior anterior , posterior
Terms of the direction proximal distal internal , external superficial , profound (deep) medial lateral ulnar radial tibial fibular
-
Axis Verticsl axis Sagital axis Coronal axis
Plane: Sagital plane Coronal plane Horizontal plane (tansverse plane)
-
locomotor system Composition:The locomotor system consists of bone joints muscles

Bones of trunk Composition: vertebrae24 sacrum 1 coccyx1 sternum1 ribs24 () Vertebrae There are 33 vertebrae in children, arranged as follows: Cervical vertebrae C.V. 7 Thoracic vertebrae T.V. 12 Lumbar vertebrae L.V. 5 Sacral vertebrae S.V. 5 sacrum Coccygeal vertebrae Co.V. 3~4 coccyx
-
1. General features of vertebraeVertebral body Vertebral arch pedicle of vertebral arch sup. and inf. Vertebral notch lamina of vertebral arch
process (7): spinous process transverse process sup. and inf. articular processes Vertebral foramen Vertebral canal Intervertebral foramen
-
(1) Cervical vertebra a. the body: small
2. The characteristics of vertebrae in each regionb. transverse foramen Carotid tubercle anterior tubercle of transverse process of C6c. spinous processes short and bifid (except 17 cervical vertebrae)d. vertebral foramen triangular and relatively large
-
Body and spinous process absent, consists of anterior and posterior arches, and two lateral massesGroove for vertebral artery
-
Vertebra prominens
-
(2) Thoracic vertebrae A. Vertebrae Body heart-shape, superior and inferior costal fovea B. Spinous processes long, point obliquely posterior and downward C.transverse costal fovea D.Articular processes: coronal
-
(3) Lumbar vertebra a.Vertebral body: Larger, kidney-shape b.vertebral foramen:. Larger and triangular c.Spinous processes: square and horizontal d.Articular processes: sagittal
-
(4) Sacrum Anterior surface: promontory, anterior sacral foramina (four pairs) Posterior surface: median sacral crest , posterior sacral foramina (four pairs), sacral hiatus sacral cornu Lateral part: auricular surface , sacral tuberosity
