topographical anatomy organization of the human body as major parts or segments Head Neck Trunk thorax, abdomen, back, & pelvis/perineum Upper limbs & lower limbs Anterioraspect of theleg
Cavities in the body Diaphragm divides body cavity into thoracic & abdominopelviccavities. Mediastinumcontains all structures of the thoracic cavity except the lungs.
Ventral Body Cavity Membranes • Parietal serosa lines internal body walls. • Visceral serosa covers the internal organs. • Cavity between two membranes filled with lubricating serous fluid that is produced by the membranes.
Serous Membranes: Named for Their Specific Cavities& Organs • Pericardium refers to heart. • Pleura refers to lungs and thoracic cavity. • Peritoneum refers to abdominopelvic cavity.
Other Body Cavities • Oral and digestive – mouth and cavities of the digestive organs • Nasal –located within and posterior to the nose • Orbital – house the eyes • Middle ear – contain bones (ossicles) that transmit sound vibrations • Synovial – joint cavities
reGIONSin the body • Head & neck • Upperlimb • Thorax • Abdomen • Back • Pelvis &Perineum • Lowerlimb
HEAD Neurocranium Skeleton of theface
NECK transitional area between base of the cranium superiorly clavicles inferiorly joins the head to the trunk and limbs major conduit for structures passing between them. several important organs with unique functions located here
UPPER LIMB • shoulder, arm, elbow, forearm, wrist, and hand • Shoulder • area of upper limb attachment to trunk • Arm • between shoulder & elbow joint • Forearm • between elbow joint & wrist joint • Hand • distal to the wrist joint
UPPER LIMB SHOULDER proximal segment of the limb overlaps parts of the trunk (thorax and back) and lower lateral neck Bone framework of the shoulder clavicle and scapula, form the pectoral girdle (shoulder girdle); proximal end of the humerus
UPPER LIMB SHOULDER overlies half of the pectoral girdle. pectoral (shoulder) girdle a bony ring formed by scapulae and clavicles completed anteriorly by theupperpartof the sternum
UPPER LIMB • AXILLA area of transition between the neck and the arm Formed by Clavicle Scapula Upperthoracic wall Humerus Related muscles
UPPER LIMB Arm first segment of the free upper limb between shoulder & elbow Humerus Forearm second longest segment of the limb between elbow & wrist (L. carpus) Radius&Ulna
Hand L. manus part of the upper limb distal to the forearm UPPER LIMB • Wrist • Palm • Dorsum of hand • Digits (fingers)
THORAX between the neck and abdomen • .
THORAcIC SKELETON • forms the osteocartilaginous thoracic cage • protectsthe thoracic viscera and some abdominal organs. 12 pairs of ribs &associated costal cartilages 12 thoracic vertebrae & intervertebral discs Sternum
ABDOMEN • between thorax & pelvis (pelvic inlet) • organs of the alimentary system and part of the urogenital system • Containment of the abdominal organs and their contents • provided by musculoaponeurotic walls anterolaterally, diaphragmsuperiorly, muscles of the pelvis inferiorly
BACK posterior aspect of the body provides the musculoskeletal axis of support for the trunk. Bony elements mainlyvertebrae + proximal elements of the ribs + superior aspects of the pelvic bones + posterior basal regions of the skull
BACK spinal cord and proximal parts of the spinal nerves send and receive information to and from most of the body.
PELVIS • from the pelvic inlet to the pelvic diaphragm part of the trunk inferoposterior to abdomen area of transition between trunk & lower limbs pelvic cavity inferiormostpart of the abdominopelviccavity • PERINEUM • between the sex organs and the anus
PelvIcgIrdle Pelvissurrounded by the pelvic girdle (bony pelvis) formed by three bones Right and left hip bones (coxal bones; pelvic bones) fusion of three bones, the ilium, ischium, and pubis Sacrum connects the vertebral column to the two femora
LOWER LIMB • Gluteal region • between the iliac crest and the fold of skin (gluteal fold) • Thigh • Knee • Leg • Ankle • Foot
GLUTEAL REGION LOWER LIMB transitional region between the trunk and free lower limbs
FEMORAL REGION LOWER LIMB between gluteal, abdominal, and perineal regions proximally knee region distally most of the femur (thigh bone)
KNEE REGION LOWER LIMB distal femur and proximal tibia head of the fibula patella (knee cap joints between these bony structures posterior region of the knee (L. poples) popliteal fossa
LOWER LIMB Legregion between knee joint & ankle joint most of the tibia (shin bone) fibula (calf bone) Ankle region (L. tarsus) talocruralregion (L. regiotalocruralis) Foot (L. pes) or foot region (L. regiopedis) distal part of the lower limb
