1 The Human Body: An Orientation: Part B
Chapter 1, part b This part will be your lab assignment. Make sure you know your anatomical terminology, anatomical regions,
Anatomical Position Standard anatomical body position: Body erect Feet slightly apart Palms facing forward
Cephalic Upper limb Frontal Acromial Orbital Brachial (arm) Nasal Antecubital Oral Antebrachial Mental (forearm) Cervical Carpal (wrist) Thoracic Manus (hand) Axillary Palmar Mammary Pollex Sternal Digital Abdominal Lower limb Umbilical Coxal (hip) Pelvic Femoral (thigh) Inguinal Patellar (groin) Crural (leg) Pubic Fibular or peroneal (genital) Pedal (foot) Thorax Tarsal (ankle) Abdomen Metatarsal Back (Dorsum) Digital (a) Anterior/Ventral Hallux Figure 1.7a

Regional Terms Two major divisions of body: Axial Head, neck, and trunk Appendicular Limbs Regional terms designate specific areas
Cephalic Upper limb Frontal Acromial Orbital Brachial (arm) Nasal Antecubital Oral Antebrachial Mental (forearm) Cervical Carpal (wrist) Thoracic Manus (hand) Axillary Palmar Mammary Pollex Sternal Digital Abdominal Lower limb Umbilical Coxal (hip) Pelvic Femoral (thigh) Inguinal Patellar (groin) Crural (leg) Pubic Fibular or peroneal (genital) Pedal (foot) Thorax Tarsal (ankle) Abdomen Metatarsal Back (Dorsum) Digital (a) Anterior/Ventral Hallux Figure 1.7a
Upper limb Cephalic Acromial Otic Brachial (arm) Occipital (back Olecranal of head) Antebrachial Cervical (forearm) Back (dorsal) Manus (hand) Scapular Metacarpal Vertebral Digital Lumbar Lower limb Sacral Femoral (thigh) Gluteal Popliteal Perineal (between Sural (calf) anus and external Fibular or peroneal genitalia) Pedal (foot) Thorax Calcaneal Abdomen Plantar Back (Dorsum) (b) Posterior/Dorsal Figure 1.7b
Body Planes Plane: Flat surface along which body or structure is cut for anatomical study
Body Planes Sagittal plane Divides body vertically into right and left parts Produces a sagittal section Midsagittal (median) plane Lies on midline Parasagittal plane Not on midline
Body Planes Frontal (coronal) plane Divides body vertically into anterior and posterior parts Transverse (horizontal) plane Divides body horizontally into superior and inferior parts Produces a cross section Oblique section Cuts made diagonally
Frontal plane Sagittal plane Transverse plane (a) Frontal section (b) Transverse section (c) Median section (through torso) (through torso, (midsagittal) inferior view) Pancreas Aorta Spleen Left and Liver Heart Spleen Liver Spinal cord Rectum Intestines right lungs Body wall Vertebral Stomach Arm Subcutaneous fat layer column Figure 1.8
Frontal plane
Transverse plane
Body Cavities Dorsal cavity Protects nervous system Two subdivisions: Cranial cavity Encases brain Vertebral cavity Encases spinal cord
Body Cavities Ventral cavity Houses internal organs (viscera) Two subdivisions (separated by diaphragm): Thoracic cavity Abdominopelvic cavity
