Comparative Vertebrate Anatomy Lecture Notes - Skeletal System II (Skull) The Vertebrate Skull consists of: 1 - neurocranium (also called endocranium or primary braincase) 2 - dermatocranium (membrane bones) 3 - splanchnocranium (or visceral skeleton) Neurocranium: 1 - protects the brain 2 - begins as cartilage that is partly or entirely replaced by bone (except in cartilaginous fishes) Cartilaginous stage: neurocranium begins as pair of parachordal & prechordal cartilages below the

Define the term Anatomy: Anatomy is the branch of biology concerned with the study of the structure of organism and their parts. The study of the structure or internal working of something. The branch of science worried with the real structure of people‚ creatures‚ also other living life form‚ particularly as revealed by separation also separation of parts. Anatomy is the study of the structure of the body and the physical relationship between its essential parts. The history of anatomy is described

Anatomy‚ physiology‚ and injury treatment and prevention are all very important when dealing with sport and entertainment. Specifically‚ in the art of ballet. It is important to know your body and how it works. This will help you learn how to move it in a certain way to achieve a skill. It is also important to know how to treat injuries when they do occur and ways to possibly prevent them in the future. Many ballet dancers are given anatomy lessons to help them better understand how to move and

Plant Genetics JANICE NALBONE Abstract This experiment is being done to show Mendel’s rule of dominance that says certain alleles are dominant and others are recessive. To show this‚ we are using tobacco seeds‚ a monohybrid cross comparing only one trait color. We are also showing Mendel’s law of segregation with a Dihybrid cross comparing two traits of color and texture. Introduction

ANATOMY & PHYSIOLOGY of the EYE Even though the eye is small‚ only about 1 inch in diameter‚ it serves a very important function -- the sense of sight. Vision is by far the most used of the five senses and is one of the primary means that we use to gather information from our surroundings. More than 75% of the information we receive about the world around us consists of visual information. The eye is often compared to a camera. Each gathers light and then transforms that light into a "picture

What genetic mutations produce the greatest risk of skin cancer? Cancer begins when one or more genes in a cell mutate. This either creates an abnormal protein or no protein at all‚ which causes mutated cells to multiply uncontrollably. The Most common gene to carry skin cancer would be the MC1R (melanocortin-1 receptor). Increasing evidence is showing that the greater number of variations in this gene‚ the greater the risk for melanoma. It also carries a more moderate risk that the CDKN2A mutation

The uppermost strand in this structure is called the coding strand. The second strand that lies below the coding strand is called the template strand. In order for a RNA polymerase to go from the upper strand to the second strand it must go through the process called transcription. First‚ the RNA polymerase must attach on to one of the genes on the coding strand on DNA. Once the RNA polymerase attaches‚ it must then begin the process called initiation. This means that the RNA polymerase opens up
