when playing contact sports‚ the joints that are covered in articular cartilage can be worn away at a more rapid rate. Indeed‚ some injuries even lead to the cartilage being taken out altogether. This is a negative effect of contact sports on the skeletal system of young people as they may well end up suffering from osteoarthritis later in life. Osteoarthritis is thought to be related to cartilage being worn down to the point that the bone is no longer protected. High impact sport is generally

The Endocrine system helps to maintain homeostasis by secreting hormones into the bloodstream‚ which travels throughout the body. This system regulates activities such as growth and development and influence emotions and behavior. The relationship of this system alongside the other body systems is how the body maintain a stable equilibrium‚ regulating the activity of the organ systems. Nervous - The endocrine system acts as a communication tool within the human body‚ working alongside with the nervous

A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (Metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as Metubine‚ would interfere with muscle contraction. In order to understand how a neuromuscular blocking agent works one must first understand the process of muscle contraction and what has to take place in order for us

The integumentary system consists of the skin‚ and its main function is to form a external body covering‚ protect deeper tissue from injury‚ synthesize vitamin D‚ and the location of cutaneous nerve receptors.

muscles like cardiac muscle move completely automatically. There are three distinct types of muscles: skeletal muscles‚ cardiac or heart muscles‚ and smooth (non-striated) muscles. Muscles provide strength‚ balance‚ posture‚ movement and heat for the body to keep warm.The Skeletal System is of both fused and separate bones connected and supported by ligaments‚ tendons‚ muscles‚ and cartilage. The skeletal system protects‚ supports‚ and helps organs; examples of the organs that it supports are the heart

our peak bone mass. The peak bone mass is usually reached by the age of 30; therefore‚ as we age formation decelerates. Essentially‚ exercising is an ethical verdict‚ especially during our matured years. One of the key elements of regulating skeletal growth is the Osteoclasts. The Osteoclasts are responsible for initiating the bone remodeling cycle. Blood vessels and nerves are able to penetrate the bone once the chondrocytes die allowing Osteoblasts to secret osteoid; this is a protein fiber

The human body consists of eleven major organ systems that maintain homeostasis: the skeletal‚ muscular‚ circulatory‚ nervous‚ respiratory‚ digestive‚ urinary‚ endocrine‚ reproductive‚ integumentary and lymphatic systems. These organ systems are dependent on each other to keep the human body in homeostasis. For example‚ the nervous and endocrine systems coordinate functions of other body systems because they allow information to be communicated throughout the body. The nervous system consists of
