Explanation Osteology is the study of bones. It involves the examination of the structure, development, and function of bones in humans and animals. This field of study is important in understanding the skeletal system and its role in supporting the body, protecting organs, and facilitating movement. Osteologists use various techniques and tools to analyze bones, such as X-rays, CT scans, and microscopic examination. They also study bone diseases and injuries to better understand their causes and develop treatments. Overall, osteology plays a crucial role in advancing our knowledge of the skeletal system and its significance in the body.

What is the skeletal system composed of ?
A.
Bones, Tendons & Collagen
B.
Tendon & Bone
C.
Bones, Cartilages & Ligaments.
D.
Cartilage & Bone
E.
Bones
Correct Answer
C. Bones, Cartilages & Ligaments.
Explanation The skeletal system is composed of bones, cartilages, and ligaments. Bones provide support and structure to the body, cartilages act as cushioning and support in joints, and ligaments connect bones to each other, providing stability and allowing movement. Tendons and collagen are not part of the skeletal system, as tendons connect muscles to bones and collagen is a protein found in various tissues of the body.

Tendons are structurally similar to ____ but attach to ____ & _____.
A.
Bones, Ligaments, Cartilage
B.
Cartilage, Bone, Muscle
C.
Muscle, Osseous Tissue, Bone
D.
Ligaments, Muscle, Bone
E.
Osseous Tissue, Bone, Collagen
Correct Answer
D. Ligaments, Muscle, Bone
Explanation Tendons are structurally similar to ligaments but attach to muscle and bone. Tendons and ligaments are both types of connective tissue that are composed mainly of collagen fibers. However, tendons specifically connect muscles to bones, allowing for movement and transmitting the force generated by the muscle to the bone. Ligaments, on the other hand, connect bones to other bones, providing stability and support to joints.

The skeleton plays at least six roles: Name 5 taking into consideration that their is two balance one that will be counted for one.
Correct Answer Support Protection Movement Electrolyte & Acid Base Balance Blood Formation
Explanation The skeleton plays a crucial role in providing support to the body, allowing us to maintain an upright posture and carry out various movements. It also protects vital organs such as the brain, heart, and lungs from injury. Additionally, the skeleton is involved in the production of blood cells through a process called hematopoiesis. Furthermore, it helps maintain the electrolyte and acid-base balance in the body, which is essential for normal physiological functioning.

Bone, or ____ is connective tissue in which the matrix is hardened by the deposition of ____ and other ____.
A.
Regular Connective Tissue, Chondroitin Sulfate, Elements
Correct Answer
C. Osseous Tissue, Calcium pHospHate, Minerals
Explanation The correct answer is Osseous Tissue, Calcium Phosphate, Minerals. Osseous tissue, also known as bone tissue, is a type of connective tissue that has a hardened matrix. The hardening of the matrix is due to the deposition of calcium phosphate and other minerals. This process gives bones their strength and rigidity.

6.
Hardening process of bone is called.
Correct Answer Mineralization Calcification
Explanation The hardening process of bone is known as mineralization or calcification. During this process, minerals such as calcium and phosphate are deposited in the bone matrix, making it harder and more rigid. This process is essential for the strength and stability of the skeletal system.
Rate this question:
7.
Hardest substance in the body?
A.
Tooth Enamel
B.
Compact (dense) Bone
C.
Medullary Cavity
D.
Endosteum
E.
Epiphyseal Plate
Correct Answer
A. Tooth Enamel
Explanation Tooth enamel is the hardest substance in the body because it is made up of a dense mineral called hydroxyapatite, which provides strength and protection to the teeth. Enamel is even harder than bone and can withstand the forces of biting and chewing. It acts as a barrier against acid erosion and protects the underlying dentin and pulp from bacteria and other harmful substances.
Explanation The correct answer is a list of tissues that make up bone. Osseous tissue is the main component of bone, providing its strength and rigidity. Adipose tissue, also known as fat tissue, is found within the bone marrow and helps to cushion and protect the bone. Nervous tissue is present in the form of nerves that innervate the bone, allowing for sensation and communication. Fibrous connective tissue, such as tendons and ligaments, attach to the bone, providing stability and support.

Bone is made up of the following:
Correct Answer Bone Marrow Blood Cartilage
Explanation Bone is made up of three main components: bone marrow, blood, and cartilage. Bone marrow is a soft, spongy tissue found inside bones that produces red and white blood cells. Blood vessels run through bone tissue, supplying oxygen and nutrients to the cells. Cartilage is a flexible connective tissue that covers the ends of bones, providing cushioning and reducing friction between bones. Together, these components contribute to the structure, function, and maintenance of bones in the human body.

C.
Organ, Osseous Tissue
D.
Organelle, Osseous Tissue
E.

Bones classifies into four organs:
Correct Answer Long Bones Short Bones Flat Bones Irregular Bones
Explanation The given answer lists the four classifications of bones: long bones, short bones, flat bones, and irregular bones. These classifications are based on the shape and structure of the bones. Long bones, as the name suggests, are longer than they are wide and have a shaft with heads at both ends. Short bones are roughly cube-shaped and provide stability and support. Flat bones are thin, flat, and curved, providing protection for internal organs. Irregular bones have complex shapes and do not fit into any other category. Therefore, the answer is a correct classification of bones based on their shapes.
