Braxton Hicks contractions

‘Protein’ plays a vital role for our body as we cannot survive without it. Protein is an important building block of bones, muscles, cartilage, skin and blood. It is also a macronutrient, means the body needs relatively large amount of it. Recently, almost everyone starting from the teenage ageto the age of 30-40 wants to stay healthy . There are bodybuilders too who are working hard to accomplish their goal, they ingest protein shakes. Since protein shakes fulfill the purpose of deliverying the…

The two main neck muscles are the sternocleidomastoid and the trapezius, and are responsible for the gross motor movement in the muscular system of the head, neck and shoulders. The sternocleidomastoid muscle is a paired muscle, located at the front and on each side of the neck. It is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. The trapezius is one of the biggest shoulder and…

The introduction of this lab report discussed and elaborated how muscle contraction is an intricate and precise step-by-step process in the body. The concepts outlined at the introduction intertwine with the experiments performed in this laboratory. The experiments aimed to showcase the physiological cause and effect of skeletal muscle response towards various settings. For instance, the first experiment demonstrated spatial summation through the form of muscle recruitment. The cause of this…

Arizona v. Hicks, 480 U.S. 321, 325 (1987). In Hicks, the officers, responding to a shooting, moved a stereo to view and recorded the serial numbers. Id. The Supreme Court held that recording the numbers was allowed, however, what was not reasonable was the action of moving the stereo…

Since the mid-1800’s, research contributing to the vast amount of information we know today about stem cells has broadened our horizons in the field of medicine, as well as led to several discoveries involving humanity’s origin. Although they comprise only a small portion of known stem cells, muscle stem cells are indeed equally as important to science because of their aid in helping us to gather new facts about the human body. Therefore, to completely understand how these cells affect our…

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 sciatic nerve and the gastrocnemius muscle to observe the level of intensity, contraction, and voltage threshold caused by different stimulation pulses. Introduction When a neuron produces an action potential it could be due to chemical…

was stimulated by one pulse in a 625 ms period after an initial 50 ms delay, each record. The minimum stimulus voltage that resulted in a measurable muscle contraction was the threshold voltage. Records were collected until three successive stimuli of increasing voltage did not increase the force generated by the resulting muscle contractions. The stimulus voltage applied to the muscle at the point where increased voltage strength ceased to increase force generation was the maximum excitation…

The ability for muscles to contract and shorten to produce movement lies within its structure at a cellular level. The muscle organ is surrounded by a fibrous connective tissue called the epimysium, continuous to the perimysium, which separates the organ into small bundles called fascicles. Each fascicle can be further separated into muscle fibers by the endomysium. The plasma membrane of an individual muscle fiber is called the sarcolemma, which plays a major role in generating an action along…

Movement of the skeleton is stimulated by the contraction of striated muscle also known as skeletal muscle. Because it is attached to the bones and skin it is responsible for the motion of the body and limbs, thus making it controlled voluntarily. There are three layers of connective tissue in the skeletal muscle known as epimysium which surrounds the entire muscle, perimysium which surrounds muscle fibers known as fascicles, and endomysium which contains capillaries and nerve fibers. Cardiac…

control lots of muscle fiber, they can form a motor unit. When we do muscle contraction, motor units are activated to send electron signal to muscles, then muscles can do contraction. According to the different physiological function, motor unit can be divided into 2 categories, kinetic motor unit and tonic motor unit. The high frequency of electron signal released when the motor unit of the muscle fiber is excited, the contraction force is strong, but is easy to fatigue, it is the fast…
