INTRODUCTION TO REGIONALANATOMY Kaan Yücel M.D., Ph.D. 19. November2013 Tuesday
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 Dorsal body cavity
Cavities in the body Ventralbody cavity
reGIONSin the body • Head & neck • Upperlimb • Thorax • Abdomen • Back • Pelvis &Perineum • Lowerlimb
HEAD Neurocranium Skeleton of theface
NECK transitional area between the head and the trunk 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
UPPER LIMB • AXILLA area of transition between the neck and the arm irregularly shaped pyramidal space
UPPER LIMB Arm first segment of the free upper limb between shoulder & elbow 1 bone Forearm second longest segment of the limb between elbow & wrist (L. carpus) 2 bones
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
SKELETON OF THE PELVIS Right hip bone Left hip bone (coxal bones; pelvic bones) • Sacrum Coccyx (tailbone)
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-THIGH LOWER LIMB between gluteal, abdominal, and perineal regions proximally knee region distally 1 bone
KNEE REGION LOWER LIMB transitional area between the thigh and the leg posterior region of the knee (L. poples) popliteal fossa
LOWER LIMB Legregion between knee joint & ankle joint 2 bones Ankle region (L. tarsus) talocruralregion (L. regiotalocruralis) Foot (L. pes) or foot region (L. regiopedis) distal part of the lower limb
Axilla Popliteal fossa (5)
