Evolution & Nature of Science Institutes (ENSI/SENSI) Lesson Plan: Making Cladograms MAKING CLADOGRAMS: Background and Procedures Phylogeny‚ Evolution‚ and Comparative Anatomy A. Concept: Modern classification is based on evolution theory. B. Background: One way to discover how groups of organisms are related to each other (phylogeny) is to compare the anatomical structures (body organs and parts) of many different organisms. Corresponding organs and other body parts that are alike in basic structure

structures toward the rear‚ or backside‚ of the body. The terms dorsal (backside) and ventral (“belly”) are used interchangeably with the terms posterior and anterior. The sternum (breast bone) is on the ventral side of the body and anterior to the vertebral column‚ while the scapula (shoulder blade) is on the dorsal side of the body and posterior to the clavicle (collarbone). The terms superior and inferior refer to the location of structures along the long axis of the body. Superior structures are above

Chapter 5: The Skeletal System I. Introduction. The skeletal system consists of the bones‚ along with the cartilage and fibrous connective tissue that make up the ligaments that connect bones to bone at joints. A. Functions of the Skeleton. 1. The skeleton supports the body. 2. The skeleton protect soft body parts. The skull protects the brain‚ the rib cage protects the heart and lungs‚ and the vertebrae protect the spinal cord. 3. The skeleton produces blood cells. Red bone marrow contains

CENTRAL NERVOUS SYSTEM The Brain -recap * The brain receives signals from inside and outside the body. * It keeps the basic‚ body functions such as heart beat rate‚ breathing rate and temperature control ticking over‚ without us having to think about it. * It also allows us to decide to do things like running and walking and many more complex tasks. It is where our personalities and moods and emotions come from. * The brain of a human being makes up about one-fiftieth of

Anatomy Outline Notes Exam 1 Developmental Anatomy – is the way anatomy changes over time in a single species -somites are segmental blocks found in embryos that form muscles & vertebrae etc. Comparative Anatomy – is the comparison of anatomies between different species. -all known vertebrates have common feature (skull & vertebrae): this leads to evolutionary theory. Hierarchy of Structural Organization -Body -> System -> Organ -> Tissue -> Cells -> Chemical/Molecular

Why do you think there are discs of cartilage between the bones in the vertebral column? There are discs of cartilage because that is what protects each vertebrate from grinding against each other‚ which would cause fractures and a lot of pain. 3. What is the difference between a true rib‚ a false rib and a floating rib?

extends down to the space between the first and second lumbar vertebrae; it does not extend the entire length of the vertebral column. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also‚ the spinal cord has a varying width‚ ranging from 1/2 inch thick in the cervical and lumbar regions to 1/4 inch thick in the thoracic area. The enclosing bony vertebral column protects the relatively shorter spinal cord. The spinal cord functions primarily in the transmission of neural signals

This is an essay on the 12 major human body systems‚ which are skeletal‚ muscular‚ nervous‚ endocrine‚ reproductive‚ respiratory‚ excretory‚ circulatory‚ integumentary‚ lymphatic‚ digestive and the immune system. Each of these systems are important for the body and help the body in its own unique way. If one fails‚ it may cause a domino effect and cause the downfall of another system. Here we are going to start with the skeletal system. The skeleton is a flexible framework that supports the body
