allantois
division foregut/midgut
liver and pancreatic buds
resists anterior translation and medial rotation of tibia, in relation to femur
anterior cruciate
prevents femur from sliding off anterior edge of tibia and prevents tibia from displacing posterior to femur
posterior cruciate
resists forces that would push knee medially
medial collateral
keeps outer side of the knee joint stable
lateral collateral
distributes over fifty percent of medial support of the elbow
ulnar collateral
protects elbow joint from twisting forces generated in pitching, serving a tennis ball or throwing a javelin
ulnar collateral
remains taut throughout extension and flexion of the joint
radial collateral
wraps around head of radius and attaches to ulna, stabilizes radius in radial notch and allows for rotating hand
annular collateral
hepatic artery, hepatic portal vein and common bile duct are called
portal triad
connects ciliary body with crystalline lens of eye
