Cardiac muscle

The skeletal muscle system is made of many skeletal muscle fibers which have at least one neuromuscular junction. A neuromuscular junction is the area of the skeletal muscle fiber that is innervated by a motor neuron (motor nerve). It plays a key role in body movement and breathing along with our nervous system. The synaptic knob, motor end plate, and the synaptic cleft are all key parts of the neuromuscular junction. The synaptic knob of an axon connects with a skeletal muscle fiber to form the…

The heart muscle is called the Myocardium. The Myocardium is the middle and thickest layer of the heart wall. The muscle functions by providing a type of “scaffolding” for the heart chambers and when contracting it pumps blood out of the heart and then relaxes as the heart refills with returning blood. The Myocardium’s smooth outer membrane is called the epicardium and its inner lining is called the endocardium. The heart muscle like any other organ or tissue in your body needs oxygen-rich…

The human body is composed of muscle which are responsible for body movement. Muscles in found in the human body attach to the bones of the skeletal system, in a human body there are “700 individual muscles that make up part of a person’s weight and the muscular system. Each of these muscles are separate organ which are made up of skeletal tissues, nerves, blood vessels and muscle tissues. Muscle tissues are found throughout the human body, inside the heart, the blood vessels and the digestive…

is composed of 640 to 850 muscles each having a different function in helping the muscular system operate. The main function of the muscular system is movement. Muscles help provide strength, endurance, and help to keep the body warm. Muscles help keep the body warm by continuously pumping blood out of the heart and by body movement. There are three main categories of muscles in the human body: skeletal, cardiac, and smooth (non-striated) muscles. One type of muscle, known as skeletal,…

have over 600 muscles in our bodies that perform a variety of functions. All muscles are made of the same tissue but within our bodies there are 3 different kinds of muscles. There are Cardiac, smooth, and skeletal muscles and each of these is found in different places. Cardiac muscles are in the walls of the heart, Smooth muscles are in the walls of organs, and skeletal muscles are attached to our skeletons. Cardiac and smooth muscles are involuntary used whereas skeletal muscles are voluntary…

first round of the zombie transaction is indeed an intoxication whose essential characteristic is that it can induce a marked weakness so that victim progresses to muscle weakness. Voluntary muscles also called life muscles are selectively affected while the smooth muscles like the muscles involved in breathing mechanics, heart muscle that is to say, those whose application is independent of the will of the subject are affected to a lesser degree. "The beating of the heart that are considered…

Exercise is very general word. There are hundred types of exercises, and they are for different reasons. For example, there are sports for avoiding diseases, building bodies, or entertainment(1). However, each one of them is important. Three aspects about exercise that will be highlighted are The definition of exercise, similarities between two exercises, and differences between another two exercises. The first aspect that will be discussed is the definition of exercise. Exercise…

strength by which a nerve or muscle fiber responds to a stimulus is independent of the strength of the stimulus. If that stimulus exceeds the threshold potential, the nerve or muscle fiber will give a complete response; otherwise, there is no response. It was first established by the American physiologist Henry Pickering Bowditch in 1871 for the contraction of heart muscle. According to him, describing the relation of response to stimulus, “An induction shock produces the muscle at the time.…

1.3.2 Papillary dermis The papillary dermis is the smaller of the two layers in the dermis, and is located between the epidermis and the reticular dermis. The papillary dermis is approximately 300-400 µm deep, depending on the age and anatomical location.22 The upper outermost layer of the papillary dermis is arranged into protruding structures called the dermal papillae. The dermal papillae contains microvascular and neural components to support the epidermis. The dermal papillae increase the…

From the time of birth to adulthood, the amount of bones in the human body decreases as they are amalgamated together to construct larger and sturdier bones. Adults have two hundred and six bones in the body; On the other hand, babies are born with approximately three hundred bones. The axial skeleton consists of eighty bones, which are part of the skull, hyoid bone, vertebral column and thoracic cage. Additionally, the appendicular skeleton consists of one hundred and twenty six bones that are…
