A Strength Training Program is Much Different Than A Bodybuilding Program. In order to setup a proper strength training routine, you need to understand how a muscle gets stronger. If you fail to understand the physiology behind getting stronger, you will put together a sub-optimal strength training program. My goal in this short article is to explain the differences between bodybuilding and gaining strength. How a Bodybuilding Program Works. Bodybuilding involves breaking down a muscle. This…

compartment (The section between the II & III MCP) a. The flexor tendons leave the carpal tunnel and enter a central compartment in the palm. This compartment contains the flexor tendons and their synovial sheaths, the lumbrical muscles, and the digital nerves and vessels (AnatomyExpert, 2014). 20. Hypothenar compartment/eminence (The section on the outside of the 5th MCP) a. This compartment contains the muscles of the hypothenar eminence which include the abductor digiti minimi, flexor digiti…

surrounds the body. The complex wall muscle is composed of the circular diagonal and muscle fibers (Newmark and Alvarado, 2001). The nervous system contains two ventral nerve cores. The nerve cores are aggregated in the anterior part of the planarian to form the cerebral ganglia that are connected to two ventral longitudinal nerve cords, which are interconnected with the lateral commissures, and a submuscular nervous plexus (Newmark and Alvarado, 2001, Wenemoser, 2011). The function of the…

said in National Institute of Neurological Disorders and Stroke “That the physicians Jean-Martin Charcot, Pierre Marie, and Howard Henry Tooth. In 1886 Charcot, Marie, and Tooth discovered a group of progressive disorders that affects the peripheral nerves” (NINDS). They still consider this disease to being rare in the United states. The estimated amount of people who are diagnosed is fewer than 175,00 a year and the worldwide estimate is around 2.5 million. Of course, this number can be much…

rupture of the ligament allows for the gel like substance or nucleus pulposus to exit the disc. Both conditions can create pressure on the corresponding spinal nerves or even on the spinal cord which leads to neurological symptoms such as pain, numbness, tingling, and weakness throughout the area serviced by the corresponding spinal nerve or area of the spinal cord”(Ashby). This can cause many problems for the patient's spine. Chiropractors can treat the symptoms by “ adjusting the corresponding…

1. The number of muscle fibers that are innervated by a motor neuron is dependent on what muscle it is. Fine motor movements, such as typing, would need only a few muscle fibers. This means that the thumb has only a few fibers, but the thigh, back, and biceps have many. These need a lot more force to be exerted, which is why they need more muscle fibers. Using your thumb and bladder does not require many muscle fibers. 2. Alpha motor neurons innervate extrafusal muscles but gamma motor neurons…

This study analyzed the differences and the relationships of the isolated sciatic nerve in regards to the compound action potential and the neuromuscular junction stimulations of the Rana pipens gastrocnemius. A total of five exercises were used to identify the effects on the stimulation of the sciatic nerve and the gastrocnemius. A dissection for both labs were performed to isolate the nerve and to isolate the gastrocnemius. Both experiments used LabChart to perform various stimulations on the…

Figure 1. An EMG Tracing of Triceps and Biceps Muscles Co-activation. EMG signal produces an electrical activity of the muscle fibers active at a moment time. The electrical activity is measured in millivolts per milliseconds. The top channel shows the bicep EMG, while the bottom EMG correlates to the triceps contraction traces. Shown on the top graph, there are two periods of bicep activation, each last approximately 1.5ms. When the biceps are activated, it produces increasing amplitude peaks,…

of all chordates. It gives the skeletal support and is found in between the digestive tube and nerve cord. In some animal chordates lifetimes it is the main axial support in the body. The dorsal hollow nerve cord is the only feature unique to all chordates. It is located at the top of the animal, above the notochord. During the development of the nerve cord the ectoderm rolls into a hollow tube. The nerve cord grows into the brain and spinal cord of most chordates which means it is part of the…
