Thorax

Thorax - Ligament Attachment Sheet. Every ligament in the reference with its attachments, function, and clinical point, grouped by body region.
LigamentAttachmentsFunctionClinical point
Central tendon of the diaphragmReceives the surrounding diaphragm fibers; attached superiorly to fibrous pericardium, with no direct insertion into boneCollects and transmits muscular force as the diaphragm descends; contains the caval passageThe pericardial attachment links this tendon anatomically to the sac around the heart
Chordae tendineaePapillary muscles or ventricular wall to the margins and ventricular surfaces of mitral or tricuspid leafletsRestrain leaflet prolapse and distribute force through the valve–ventricle apparatus during systoleDisrupted chordal support can produce a flail leaflet segment and valvar regurgitation
Fibrous skeleton of the heartConnective tissues at valve attachments, including right and left fibrous trigones, aortic–mitral continuity and the membranous septal regionSupports valves and myocardium and electrically separates ordinary atrial and ventricular muscleThe nearby penetrating atrioventricular bundle can be affected by disease or procedures around the central fibrous body

Abdomen

Abdomen - Ligament Attachment Sheet. Every ligament in the reference with its attachments, function, and clinical point, grouped by body region.
LigamentAttachmentsFunctionClinical point
Coronary and triangular ligamentsCoronary layers reflect between diaphragm and posterior/superior liver; the right triangular ligament joins their lateral margins, and the left triangular reflection attaches the lateral left lobe to the diaphragm.Help stabilize the liver relative to the diaphragm while permitting respiratory movement; fixation is also supported by the caval and other attachments.These folds define planes relevant to liver mobilization and nearby hiatal exposure. Their continuity helps explain why posterior hepatic attachments relate to extraperitoneal tissue.
Falciform ligamentReflects from the anterior abdominal wall and diaphragm onto the anterior/superior liver; its inferior margin extends toward the umbilicus and its upper layers continue into adjacent hepatic reflections.Provides a peritoneal attachment and surface landmark while partly separating the subphrenic peritoneal spaces.Paraumbilical venous channels in this region may enlarge in portal hypertension. They should not all be described as a reopened single fetal umbilical vein, and the fold does not seal the recesses into completely isolated cavities.
Gastrosplenic ligamentExtends from the fundal/upper greater-curvature region to the hilum of the spleen.Links the stomach and spleen while carrying short gastric and left gastro-omental vessels with accompanying lymphatics.These vessels matter during mobilization of the stomach or spleen. The short gastric venous route can become a collateral pathway when splenic venous outflow is obstructed, producing gastric varices.

Pelvis

Pelvis - Ligament Attachment Sheet. Every ligament in the reference with its attachments, function, and clinical point, grouped by body region.
LigamentAttachmentsFunctionClinical point
Broad ligamentExtends laterally from the uterus to the pelvic wall; its superior part surrounds the tube, and the mesovarium attaches to its posterior aspect.Organizes the adnexa and provides peritoneal coverings around pathways for vessels and other structures. Major apical support also depends on cardinal–uterosacral connective tissue and the pelvic floor.Paratubal cysts and masses may occur within or near its layers; enlarging lesions can distort the adjacent ureter and vascular pedicles.
Cardinal (transverse cervical) ligamentExtends from the lateral cervix and upper vagina toward connective tissue around the internal iliac vascular region of the pelvic sidewall.Provides apical support with the uterosacral complex and contains vascular, neural and connective-tissue components.The uterine artery crosses the ureter near the cervix within this broader paracervical region; their distances vary between individuals.
External spermatic fasciaContinuous proximally with fascia at the margins of the superficial inguinal ring and the external oblique aponeurotic region.Forms a thin outer investment of the spermatic cord and continues into the coverings around the testis.Its relationship to deeper cremasteric and internal spermatic layers helps explain the coverings of an indirect inguinal hernia.

Back

Back - Ligament Attachment Sheet. Every ligament in the reference with its attachments, function, and clinical point, grouped by body region.
LigamentAttachmentsFunctionClinical point
Denticulate ligamentsPial bands on the lateral cord surfaces connect to dura through triangular extensions passing across the subarachnoid spaceHelp restrain cord displacement while permitting movement; the amount and direction of restraint vary by spinal regionUseful for orientation between dorsal and ventral roots during intradural surgery; their presence does not make the cord immobile
Filum terminaleConus tip to the lower dural sac as the filum terminale internum, then onward with a dural contribution toward coccygeal attachments as the externumContributes to longitudinal support of the lower cord and dural sac while accommodating movementA thickened or fatty filum can accompany tethering, but fat within the filum is often an incidental MRI finding and does not alone establish symptomatic tethered cord

Head & neck

Head & neck - Ligament Attachment Sheet. Every ligament in the reference with its attachments, function, and clinical point, grouped by body region.
LigamentAttachmentsFunctionClinical point
Cricothyroid ligamentCricoid superior border below; thyroid angle anteriorly and arytenoid vocal processes posteriorly. The median portion directly joins the thyroid and cricoid in front.Supports the subglottic wall and forms the vocal ligaments along its superior margins, transmitting forces between the laryngeal cartilages.The median ligament is an emergency airway landmark. Nearby and crossing vessels explain bleeding risk; this anatomical description is not a procedural guide.
Diaphragma sellaeSpans the sellar roof between the tuberculum sellae anteriorly and dorsum sellae posteriorly, blending laterally with adjacent duraSeparates much of the pituitary fossa from the suprasellar compartment while allowing passage of the stalk and vesselsSuprasellar extension may compress crossing optic fibers, producing the classic bitemporal visual-field pattern
Falx cerebriAnterior attachment to the frontal crest and crista galli; superior attachment along the cranial midline; posterior continuity with the tentorium near the internal occipital protuberanceSupports separation of the hemispheres and limits relative displacement; its margins and posterior junction contain major venous sinusesIn subfalcine herniation, medial cerebral tissue is displaced beneath the falx's free inferior margin
