The spine is a set of 33 vertebrae and is connected to the brain (the other component of the CNS). There are 3 main functions of the spine: Movement and Flexibility – Since the spine is made up of 33 vertebrae, the spine can flex in every direction. This allows humans to do simple tasks […]

Skin Anatomy
The skin is the largest organ in the entire body. It is composed of many layers of tissue and is full of nerve endings, blood vessels and hair follicles. The skin has many different functions, those of which will be explored in this page. Skin cells are constantly being replaced, and it takes around a […]
Sickle Cell Anaemia
Sickle Cell Anaemia affects the haemoglobin in red blood cells, which carry oxygen from the lungs to all parts of the body. Sickle cell anaemia is a genetic condition where the red blood cells are not a normal (biconcave) shape. Instead, they look like sickles. Due to it being genetic, people are born with this […]
Cervical Collars
Cervical collars are specifically designed to immobilise the part of the spine in someone’s neck. These will be used when a patient has a suspected spinal injury. After things such as car crashes, most people involved may be fitted with cervical collars. You need to fit one onto a casualty with the greatest care. This […]
Aerobic Respiration
Respiration is one of the seven characteristics of life. Without it, life would not be possible. Respiration is the conversion of food chemicals into waste products and a chemical which provides energy for life. There are a few different types of respiration, the main of which is aerobic respiration. The other main type of respiration […]
The Muscular System
The muscular system consists of three main types of muscle tissue. There is smooth tissue, cardiac tissue and skeletal tissue. Muscles make up a lot of the nervous system (although they can be a part of other systems as well). Two certain proteins form the majority of muscles: actin and myosin. These protein strands overlap […]
Knife Wounds
When dealing with any sort of victim of a knife attack, your safety must come first. There is no point seeing someone get stabbed, immediately running over to help them and then getting stabbed yourself as well. So, always make sure that the assailant has left the area before you approach the patient. If you […]
Laryngectomies
Laryngectomies, like tracheostomies, are another airway management tool. Laryngectomies tend to be inserted when people have had cancers of the voice box and had the airway itself altered. The trachea, which normally reaches the mouth and nose, is sealed off where the voice box used to be. The only entry for air to go into […]
Common Skeletal Injuries
The human body has 206 bones, and all of these are able to break. Any break of a bones, whether that be a tiny fracture, chip or the bone completely shattering, it is called a bone fracture. Here are some of the most common bones to become injured. Skull (Cranium) Injuries to the skull will […]
The Circulatory System
The heart is one of the most important organs in mammals and is made of muscular tissue. It pumps blood around the body to other vital organs, giving them oxygen for aerobic respiration. In one circulation of the body, blood enters and leaves the heart twice. Arteries and veins carry blood around the body. Arteries […]
