The Visible Human Project – a guy on death row had his body donated to science and it was sliced up so can reconstruct it 3 dimensionally. Finding your way around the body Planes o Sagittal plane – bilateral bisection through the body (right down the middle) is called the mid-sagittal plane. – Slice down the midline o Frontal plane – separates front from back o Transverse plane – separates top from bottom Oto|rhino|laryng|ology ear|nose|throat|study of Major regions of the body o Axial region – central axis of the body, includes: Head Neck Trunk region/ torso o Appendicular region – extremities (arms, legs) Directional Terms o Superior vs. Inferior – up vs. down o Cranial vs. Caudal – cranium vs. tail o Anterior vs. Posterior – directionality of body – intestines are anterior to spinal cord, toes are anterior to heels.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
