Describe what is happening in each phase. a) latent- is a short period between the time of stimulation and the beginning of contraction b). Contraction – at this stage the muscle reaches its peak in contraction. Relaxation -Muscle is shortened‚ returns to zero and back initial length.

loses body heat easily. There are four sources of heat loss in newborns such as evaporation‚ conduction‚ convection‚ and radiation. Evaporation is when fluid evaporates from the skin due to sensible (sweating) or insensible (skin and breathing) losses. There are also other factors that contribute to evaporation and newborns‚ vapor pressure and air velocity is the main cause of newborn’s heat loss. Conduction is when the newborns are placed on a cool surface. The transfer of heat between two objects

Sclerosis and today that affects more than 2.1 million people worldwide. MS is a chronic autoimmune disorder caused by the destruction of the myelin sheath that covers nerve fibers in the CNS. Myelin is the insulator of nerve conduction and it allows the signals to travel at fast speeds. During MS‚ demyelination occurs causing the nerves to fire at a slower rate than usual‚ making them fatigue more quickly. People with this disorder often have a variety of symptoms including problems with vision‚ strength

Excitation-contraction coupling is the combination of the electrical and mechanical events in the muscle fibres and is related by the release of calcium from the sarcoplasmic reticulum. (Silverthorn‚ 2007) In the skeletal muscle‚ action potential in the nerves is generated when the somatic motor neurons releases the neurotransmitter acetylcholine (ACh)‚ at the neuromuscular junction. This initiates muscle action potential which is then transmitted to the t-tubules. Action potential in the t-tubules leads

United States. Since it is rare‚ all forms can be deadly and are considered to be medical emergencies. The cause is a neurotoxin made by a bacterium called Clostridium botulinum (C. botulinum). This toxin travels through the blood to attach to the nerves that control muscles. From several hours to a week after eating contaminated food‚ the person may get sick. Medical descriptions of botulism traces as far back in history as ancient Rome and Greece civilzations. However‚ the relationship between
