| third trochanter | An occasional process at the proximal end of the lateral lip of the linea aspera of the femur, about on a level with the lesser trochanter, giving insertion to the greater part of the gluteus maximus muscle. See: gluteal tuberosity. (05 Mar 2000) |

| greater trochanter | A strong process at the proximal and lateral part of the shaft of the femur, overhanging the root of the neck; it gives attachment to the gluteus medius and minimus, piriformis, obturator internus and externus, and gemelli muscles. Synonym: trochanter major. (05 Mar 2000) |
|---|---|
| small trochanter | A pyramidal process projecting from the medial and proximal part of the shaft of the femur at the line of junction of the shaft and the neck; it receives the insertion of the psoas major and iliacus (iliopsoas) muscles. Synonym: trochanter minor, small trochanter, trochantin. (05 Mar 2000) |

| trochanter tertius | The point of insertion on the upper portion of the shaft of the femur of the greater part of the gluteus maximus muscle; when markedly developed this tuberosity is called the third trochanter.

| choroid plexus of third ventricle | The double row of vascular projections from the undersurface of the tela choroidea where it roofs over the third ventricle. Synonym: plexus choroideus ventriculi tertii. (05 Mar 2000) |
| choroid tela of third ventricle | A double fold of pia mater, enclosing subarachnoid trabeculae, between the fornix above and the epithelial roof of the third ventricle and the thalami below; at each lateral margin is a vascular fringe projecting into the choroidal fissure of the lateral ventricle; on its undersurface are several small vascular projections filling the folds of the ependymal roof of the third ventricle.
