The Axial and Appedicular Skeleton

The Axial and Appendicular frame of reference Laszlo Vass, Ed. D. stochastic variable 42-0021-00-01 Lab RepoRt assistant This document is not meant to be a substitute for a earnal laboratory report. The Lab Report attendant is simply a summary of the experiments questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to hasten students writing of lab reports by providing this information in an editable file which toilet be sent to an instructor. Purpose ? What is the purpose of this exercise? ?Are there any safety concerns associated with this exercise?If so, list what they ar and what precautions should be taken. answer 1 The Skull Questions A. Name the eight finger cymbals of the braincase. The eight bones of the cranium argon the frontage, occipital, left parietal, right parietal, left temporal, right temporal, ethmoid, and sphenoid. B. What service do the cranial bones serve? The cranial bones serve to comfort v ariety meat, such as the tickers, and the brain. C. List the bones that form the eye orbit. Zygomas, maxilla, lacrimal, frontal bone, sphenoid, ethmoid and palatine be all the bones that form the eye orbit.D. Examine the skull on the skeleton model and describe many ways in which the mandible is different from the other bones of the skull. The mandible is a joint that has no real attachment to any part of the embody. It has a different range of motion than other joints in the body. E. Other than the skull, what ar the other two components of the axial skeleton? xVertebral Column and Thoracic batting cage argon two components of the axial skeleton. Exercise 2 Skull Markings Questions A. Which bone is palpated when spot the forehead?The temporal bone is palpated when the forehead is touched. B. What bone is palpated when touching the tabernacle? The temporal bone is touched. Exercise 3 The Vertebral Column Questions A. What are the five categories of vertebrae in your vertebra l column? Cervical, Thoracic, Lumbar, Sacral and Coccyx are the five categories of the vertebrae. B. wherefore are lumbar vertebrae particularly prone to wounding? A lot of individuals use their back instead of their legs to lift something heavy, which puts underline on the overturn back. C. What is an intervertebral disc?What is its function? They are discs that are made of fibrocartilage and they are used to cushion the spine from shock. D. How are the sacrum and tail bone different from the other vertebrae? The vertebrae in these column sections are fused in concert as opposed to separately stacked. E. What is the overall function of vertebrae? It is one of the bodys major structure supports. It encloses the spinal cord and keeps the nerves from enough damaged. Exercise 4 The Bony Thorax Questions A. What bones make up the bony thorax?The sternum, the ribs, and thoracic vertebrae make up the bony thorax. B. What is the function of the bony thorax? The function of the bony t horax is to protect the organs that are there. C. What category of bones are the sternum and ribs? The sternum and ribs are considered flat bones. D. Why are ribs 11 and 12 referred to as drift ribs? These two ribs are considered floating ribs because they arent attached directly to the sternum, hardly they are held on by cartilage. E. Propose a reason why the ribs are attached anteriorly by cartilage.A logical reason to why the ribs are attached anteriorly by cartilage is because of how the body flexes duration still being able to protect some of the other springy organs in the thoracic cavity. Exercise 5 The Appendicular Skeleton Questions A. What is the pelvic girdle? What is its function? The pelvic girdle is where two coxal bones are placed. The take the weight of the body and is what the two lower extremities are attached to. B. What is the pectoral girdle? What is its function? This is where the scapula and the clavicle form the upper part of the body.This attaches the up per extremities to the core and is a main witness of strength for the neck and upper body. C. Name the bones of the upper appendages (arm, arm and hand). The upper appendage consist of the Humerus, Radius, Ulna, Olecranon Process, Carpals, Metacarpals and the Phalanges. D. Name the bones of the lower appendages (thigh, leg and foot). The lower appendage consists of the Femur, Patella, Tibia, Fibula, Tarsals, Talus, Calcaneus, Metatarsals and the Phalanges. E. Which of the four categories of bones do roughly of the bones of the appendicular skeleton fit into?Most of the bones in the human body are categorized as long bones. Conclusions Why is it important to relate the structures of the axial and appendicular skeleton to one another(prenominal)? It is important to relate the structure of the axial and appendicular skeleton because some of the bones function differently, yet visit the same or they look the same and have different functions (i. e. legs are for walking while muniti on are for holding). A lot of the other bones form a structure for weight bearing and others are more shock absorbers.
