After landing on an unexplored Klingon planet,Spock tests for the direction of the magnetic field by firing a beam of electrons in various directions and by recording the following observations:
Electrons moving upward feel a magnetic force in the northwest direction.
Electrons moving horizontally toward the north are pushed downward.
Electrons moving horizontally toward the southeast are pushed upward.
Mr.Spock therefore concludes that the magnetic field at this landing site is in which direction?
Nasolacrimal Duct
The nasolacrimal duct is a tube that drains tears from the eye into the nasal cavity, allowing for tear drainage and removal of debris.
Puncta
Small openings located at the inner corner of the eyelids, serving as the entrance to the tear drainage system.
Visual Pathways
The route by which visual signals travel from the eye to the brain for processing and interpretation.
Retina
The light-sensitive layer of tissue at the back of the inner eye, which converts light rays into nerve signals that are sent to the brain to create visual images.
