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...

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.

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...
