C) A skull that has been excavated will most likely be missing the ethmoid bone‚ nasal bones‚ and nasal concahe due to their delicate nature. D) Hassan and his team are able to determine the approximate ages of the skeletal remains by looking for a couple of key skeletal changes. The amount fusing of the sacrum and coccyx on the woman’s skeleton would give Hassan and his team a good indication of the woman’s age when she passed away. Hassan and his team would also be able to determine the

C. What delicate skeletal structures are found inside the nasal cavity that might be missing from an excavated skull? The skeletal structures that are found inside the nasal cavity that might be missing from an excavated skull are perpendicular Plate‚ middle & inferior nasal concha‚ and the vomer. D. How would Hassan and his team be able to tell the ages of the skeletal remains of the woman and baby? Hassan and his team would be able to tell the ages of the skeletal remains by the four

AP I Chapter 8- Joints of the Skeletal System 1) What is a joint? Functional junctions between bones 2) How are joints classified? Structurally: fibrous‚ cartilaginous‚ synovial Functionally: immovable‚ slightly moveable‚ freely moveable 3) Describe the 3 types of fibrous joints. • Syndemosis: sheet or bundle of dense connective tissue • Sutures: only between flat bones of skull • Gomphosis: binds teeth to bony sockets 4) What is the function of the fontanels? Allows the skull to slightly

because the torus is continuous with the mandibular cortex. Torus mandibularis have been associated with age‚ gender and dental status; although both genetic and environmental factors may also play a role in the formation of torus‚ the masticatory system should be considered as the primary essential initiative factor. The research conducted by Uysal‚ Cagirankaya and Hatipoglu determined the effect of gender on Mandibular Cortical Index (MCI) and verified the relationship between

The Skeletal System: Osteoporosis Case Study 1 Ann is an 82 year-old Caucasian woman. She enjoys spending her time knitting‚ reading books‚ watching old movies‚ and writing letters to her grandchildren. She recently fell while stepping out of the bathtub. Although she did not fall very far or land very hard‚ she broke her femur. The doctor in the emergency room placed her leg in a cast and tested her bone mass density‚ finding that it was low. He told Ann that she might have osteoporosis

The more detail you can provide the better prepared for the test you will be. 1. What is the integumentary system and its primary characteristics? - the skin and its derivates (sweat and oil glands‚ hairs and nails) - provides external protection for the body 2. Describe and give at least one example of each of the functions of the integumentary system. 1. Protection- skin secretions 2. body temperature regulation- production of copious amounts of sweat

life. Humans spines have evolved to bear weight and stress which will also cause humans to have back injuries and back pain later in life. When humans began walking on two legs‚ which caused a series of modifications to take place in the human skeletal system. In humans‚ the spinal cord comes out of the base of the skull‚ called the foramen magnum and goes straight downwards. While in chimpanzees the spinal cord comes out of the back of the skull. The chimpanzees pelvis is long and narrow. Humans pelvis

glass slides or electronic images of histological specimens‚ classify the cells and tissues‚ comparing their locations and functions and how they contribute to the well being of the body as a whole. 3 Given an illustration of the integumentary system analyze the structures and functions of its parts and relate them to various medical conditions. 4 Given a physical model or an electronic image of the human skeleton identify the different types of cartilages and bones and compare their structures
Premium Bone Skeletal system Muscle
Most of our skeletal muscles are attached to bone on either end by tendons. As the muscles contract‚ they exert force on the bones. This force helps to support and move our body. Normally one end of the muscle is fixed in its position and the other end moves during contraction. The Origin is the attachment site that is stationary during contraction. The insertion is the site that does move when a muscle contracts. When we discuss the position of the Origin and insertion points‚ the insertion
