Muscle Change in People Anatomy and Physiology Professor Debra Low Discussion Board Stephanie Quinn March11‚ 2013 Which lower extremity muscles are utilized during standing and walking? They are your Quadriceps they are the biggest muscles by far they are at the front of the thighs. They raise the thigh and leg. Then there are the Hamstrings these form the back of the thighs and move the leg backward. The Buttocks powerful and bulky complete the backward movement of the step. Stomach muscles

I. ANATOMY AND PHYSIOLOGY OF THE HEART I. LOCATION OF THE HEART The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist‚ and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava‚ the pulmonary artery and vein‚ as well as the aorta. The aortic arch lies

Function of the Skeletal System 1. Support 2. Movement: The bones of the upper and lower limbs pull and push‚ with the help of muscles. 3 storage as a mineral store. 97% of the body’s calcium is stored in bone. Here it is easily available and turns over fast. In pregnancy the demands of the fetus for calcium require a suitable diet and after menopause hormonal control of calcium levels may be impaired: calcium leaches out leaving brittle osteoporotic bones. 4.

Muscle Contraction & Excitation Muscle excitation takes place when there is a synaptic transmission and induction of an impulse. There are six steps that take place during muscle excitation. (1)The action potential travels down the somatic motor neuron axon reaching the synaptic bulb causing calcium ions to flow into the synaptic bulb. (2)The increase of calcium in the synaptic bulb causes the synaptic vesicles to undergo exocytosis. (Exocytosis a process that allows large molecule to leave

1. Describe the main muscle groups of the body and their function There are three main categories that the muscles in the human body fall into: • Skeletal Muscle Skeletal muscle is the foremost area of concern for a sports masseuse. The main functions of this muscle group is to move the body in a voluntary manner‚ for example‚ if you want to kick a ball you will voluntarily have to send a signal through your brain to inform the muscles in your legs to contract/flex/extend and execute the skill
