Overview of the Skeletal EssayThe purpose of this mould is to learn the skeletal musical arrangements and the components associated with the system. I will be exploring the major types of tog outs and cartilage. Are there every safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. Handle the microscope and the slides with care when taking the crybaby devise out of the oven use caution because the tusk is extremely hot. The Chemical Components of Bone Questions A. Describe the effect that the dirty dog juice (acid) had on the chicken leg bone.The Lemon juice caused the bone to change colors and disclose B. Describe the effect that baking (heat) had on the chicken leg bone. The bone is really dry and toffee I also noticed the color of the bone changed C. Rickets is a disease where the bones are not formed completely in children due to a lack of Vitamin D. Does the heated or acid-soaked bone represent a child with r ickets? Explain why. The acid-soak bone represents a child with rickets, when the bones arent getting enough Vitamin D the bones softens and tend to bend. When the bones harden back up they expect in the shape it was bent when it was softened.Exercise 2 Microscopic Structure of Bone obseRvations keep up the social structure of the Haversian system. Sketch what is seen and identify the following central canal, lacunae, concentric lamellae, canaliculi and an osteocyte. earn attached photo Questions A. Which articulation of the Haversian system was the hardest to see on the slide of compact bone? Why do you suppose this is? Osteocytes are the hardest part to see on the slide because they are so small. B. Which structures in the compact bone hark back nutrients to the osteocytes? Canaliculi deliver nutrients to osteocytes through haversian canal.C. Which structures are found inside the central canal? Cerebrospinal fluid Spinal cord Exercise 3 Structure of a Long Bone obseRvation s A. From step 4 in the procedures Observe the epiphysis. Identify as many of the following structures as possible articular cartilage, compact bone, spongy bone and bone marrow. Make a sketch of the bone in the Lab Report and label the structures you identified. See Attached photo B. From step 5 in the procedures Observe the section of diaphysis. Identify as many of the following structures as possible periosteum, compact bone, endosteum and bone marrow.Make a sketch of the diaphysis in the Lab Report and label the structures you identified. See Attached photo Questions A. How does the femur of the skeletal model equate to the diagrams in your textbook or this manual? The model and the diagrams match. The only difference is the sizes and the detail B. Using your chicken bone, how does the texture of articular cartilage (or hyaline cartilage) compare to that of periosteum? Note Articular cartilage (made of hyaline cartilage) is found on the ends of the bones. It absorbs compression and allows for smooth movement. C. What is the function of spongy bone?
