Cardiac Pacemakers
Cardiac Pacemakers CARDIAC PACEMAKERS The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through regular electrical impulses that propagate from the right atria to the lower ventricles. The rapid conduction of these impulses cause the muscle cells of the atria to...

Spinal Cord Injuries
Spinal Cord Injuries As an Emergency Medical Technician (EMT), when someone has a spinal injury, additional movement may cause further damage to the spine. EMT's must always immobilize the patient's head and torso in the position found. The purpose of an EMT is to prevent further harm to the patient until more professional medical help can be obtained. If in doubt about whether a person has received a spinal injury, always assume he or she has. A spinal cord injury (SCI) is very serious because ...

Ceriodaphnia
Ceriodaphnia Anatomy: Ceriodaphnia has six pairs of lobed legs which bear numerous hairs. Their head is bent downwards and is set from the body by a cervical sinus. The head also has two large secondary antennas that are positioned laterally near the posterior margin. (Pennak, 1989) The Ceriodaphnia's mouth is located near the junction of the head and body. The Ceriodaphnia's body is covered by a carapace which allows protrusion of only the head and abdomen. One of the Ceriodaphnia's most notic...

Osteogenesis Imperfecta
Osteogenesis Imperfecta Osteogenesis imperfecta (OI) is a rare genetic disorder of collagen synthesis associated with broad spectrum of musculoskeletal problems, most notably bowing and fractures of the extremities, muscle weakness, laxity in the ligaments, and spinal deformities.(Binder, 386). Other collagen-containing skeletal tissues, such as the sclerae, the teeth, and the heart valves are also affected to a variable degree. OI has a common feature of bony fragility associated with defective...

Lumbar Disc Problems
Lumbar Disc Problems Summary The lumbar region of the human spine is a location that is very susceptible to injury and trauma. A majority of the population experience back pain at some time during their life, and although in most cases the pain subsides after a time of rest, there is an enormous need for treatment of this malady. The various types of treatment for lumbar disc herniations include a more conservative method of rest, physical therapy, and anti-inflammatory or non-steroidal drugs. A...

Sculpins
Sculpins Reproduction and early life history of the Sculpin Have you ever personally thought that fish were an interesting subject? Most people dont. The majority of individuals consider fish ordinary, routine and insignificant. However with a closer look, you may discover that fish can be extraordinary and extremely significant in more ways than one. With proper education and better understanding, people will not only realize the importance of the fish, but also the relevance of issues such as...

Disorders DEFINITION Osteogenisis imperfecta (OI) is ?a rare genetic disorder of collagen synthesis associated with broad spectrum of musculoskeletal problems, most notably bowing and fractures of the extremities, muscle weakness, ligamentous laxity, and spinal deformities.? (Binder, 386). Other collagen-containing extraskeletal tissues, such as the sclerae, the teeth, and the heart valves are also affected to a variable degree. OI has a ?common feature of bony fragility associated with defectiv...
