Anatomical Terminology from Lab Manual
| Term | Definition | Examples |
|---|---|---|
| Anatomical position | 1-body erect; 2-face forward; 3-upper lims at the side of the body; 4-palms forward; 5-lower limbs parallel; 6-feet pointed forward | |
| Divisions of Anatomy | 1-gross:macroscopic; 2-microscopic; 3-developmental (study of individual from conception to death) | |
| Different wasy of studying gross anatomy | regional, systemic, surface | |
| microscopic | cytology (cells), histology (tissues) | |
| developmental | intrauterine (embryonic-1st 2 months gestation and fetal-3rd to 9 months) and extrauterine (birth (parturition) to death | |
| Body planes & sections | median, saggital, frontal, horizontal | |
| median plane | divides the body into equal right & left halves | |
| saggital plane | vertical planes parallel to the median plane | |
| frontal plane | vertical plane dividing the body intor anterior and posterior parts | |
| horizontal plane (transaxial) | divides the body into superior and inferior parts | |
| regional terms | axial and appendicular | |
| axial | head, neck, trunk (thorax, abdomen, pelvis) | |
| appendicular | upper and lower limb plus pectoral girdle (clavicle and scapula) and pelvic girdle (os coxae-hip bone) | |
| superior | toward the head | the heart is superior to the liver |
| inferior | toward the feet | the stomach is inferior to the lungs |
| anterior | toward the front of the body | the sternum is anterior to the heart |
| posterior | toward the back of the body | the esophagus is posterior to the trachea |
| medial | toward the median plane | the ulna is medial to the radius |
| lateral | further from the medial plane | the lungs are lateral to the heart |
| proximal | nearer the trunk or point of origin | the humerus is proximal to the radius |
| distal | away from the trunk or point of origin | the phalanges are distal to the carpals |
| superficial | near the surface | the ribs are superficial to the lungs |
| deep | away from the surface (profundus) | the ribs are deep to the skin of the chest and back |
| dorsum | back of hand or superior surface of foot | |
| palmar | anterior surface of hand | |
| plantar | sole of the foot | |
| ipsilateral | on the same side | |
| contralateral | on the opposite side |
