What is the function of fossa? What is the function of tubercle? And what is the function of a foramen?

Fossa - A shallow depression in the bone surface. Here it may receive another articulating bone, or act to support brain structures. Examples include trochlear fossa, posterior, middle, and anterior cranial fossa.

Foramen - A hole through which nerves and blood vessels pass. Examples include supraorbital foramen, infraorbital foramen, and mental foramen on the cranium.

Tubercle - A small, rounded prominence where connective tissues attach. Examples include the greater and lesser tubercle of the humerus.

Explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
