The femoral nerve lies outside the femoral triangle because it originates from the lumbar plexus and travels deep to the inguinal ligament before entering the thigh. This positioning allows it to provide motor and sensory innervation to the anterior compartment of the thigh, while the femoral triangle primarily contains the femoral artery, vein, and lymphatics. The anatomical separation helps protect the nerve from potential injury during surgical procedures or trauma in the region.

Why femoral nerve lies outside from femoral triangle?
The femoral sheath is a downward prolongation of abdominal fascial lining into the lower limbs. It covers the femoral vessels and lymphatics for about 1.5 inches into the thigh. But the femoral nerve, which is the principal nerve of lower limb, lies outside this sheath. The reason is that the major nerves lie outside the fascial envelope.
The orthocenter of a triangle may lie outside the triangle since the altitude may not intersect any side of the triangle?
The orthocenter of a triangle may lie outside the triangle because an altitude does not necessarily intersect the sides of the triangle.
Does the orthocenter always lie outside of the triangle?
No.
Can a circumcenter lie outside the triangle?
Yes, it can.

The orthocenter of a triangle may lie outside the triangle since the may not intersect any side of the triangle?
True for an obtuse triangle!
The orthocenter of a triangle may lie outside the triangle since?
The orthocenter is the point where the altitudes of a triangle intersect. An orthocenter lies outside of a triangle only when the triangle is obtuse. If a triangle is acute, the orthocenter lies inside of the triangle.
The orthocenter of a triangle may lie outside the triangle because the altitude does not necessairly intersect the of the triangle?
The orthocenter of a triangle may lie outside the triangle since the ___altitude___ may not intersect any side of the triangle. * * * * * No. One of the altitudes must intersect the side opposite it and so it is not correct to say ANY side of the triangle.
What are the circutances for an altitude to lie outside a triangles?
It must be an obtuse angled triangle.
Does the common femoral vein lie medial or lateral to the common femoral artery?
The common femoral vein is medial to the common femoral artery. The common femoral artery lies farther from the body's midline.
When will the circumcenter lie be inside the triangle?
The circumcenter of a triangle will lie inside the triangle if the triangle is acute, meaning all its angles are less than 90 degrees. In this case, the perpendicular bisectors of the triangle's sides intersect at a point that is located within the triangle. Conversely, if the triangle is obtuse (one angle greater than 90 degrees), the circumcenter will lie outside the triangle. For right triangles, the circumcenter lies at the midpoint of the hypotenuse.
