There are 7 different limb bones in the skeleton. The humerus in both arms are the longest bone in both arms. A lot more powerful bones that manipulate the upper arm just at the shoulder‚ at the elbow are all situated for the humerus.(8) The radius is the shorter of the two bones in the forearm. The radius is located on the thumb side of the forearm and allows rotation to allow to the hand to move about at the wrist.(9) The ulna is one of the most important bones to the form arm as it does give

Module 04 Case Study: Bone Tissue Part I— “Marissa” Questions 1. Describe bone tissue and the role each component plays in bone physiology and remodeling. What is the difference between compact and spongy bone? (2 points) Spongy bone looks like a sponge hence the name and contains a lot of red bone marrow (medulla ossium rubra). Red bone marrow is what produces red blood cells. Compact bones which consists of medulla ossium flava or yellow bone marrow‚ is made mostly of fat cells (Openstax College

Bone‚ in the human body‚ performs a number of mechanical and physiological functions‚ including mechanical support‚ movement and protection of vital organs. It is a complex tissue that undergoes constant repair and remodelling to its micro-architecture caused as a result of biomechanical forces imparting trauma and homeostatic insults. [1] The basic unit of bone is an osteon‚ which is made up of concentric lamellae of compact bone surrounded by a Haversian canal. There are two components to bone

INTRODUCTION Bone plays an essential role especially among higher animals because of its dynamic properties. It is a highly vascularized tissue with a unique capacity to heal and remodel without leaving a scar (Sommerfeldt‚ et.al‚ 2001). Furthermore‚ its primary function is to provide structural support of the body and has the capacity to store minerals‚ support muscle contraction resulting in motion‚ bears the load of the body and protects internal organs.
