EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to contract or dilate

The Physiology of Fitness Assignment 1 Helpsheet Step 1 You need to introduce your assignment‚ here I would define two key terms for the entire of this assignment these are chronic and acute. Example Answer There are many changes to the body during exercise; these can be classified as acute and chronic. Acute meaning they are short term and happen almost instantly with the onset of exercise. The other chronic is long term and allows the body to adapt its capabilities so therefore it

regeneration‚ become two. Planarians are hermaphrodites and contain both eggs and sperm. (2) VI. Size: Planarians range in size from the 0.125- 1 inch. However‚ there are tropical terrestrial species that grow as large as 2 feet. (4) VII. Human Interest: Planarians are found in many experiments all over the world due to their amazing regenerating abilities. In particular‚ there were many famous experiments done in the 1960s by a biologist named John McConnell. He studied the effects of memory

ANATOMY & PHYSIOLOGY of the EYE Even though the eye is small‚ only about 1 inch in diameter‚ it serves a very important function -- the sense of sight. Vision is by far the most used of the five senses and is one of the primary means that we use to gather information from our surroundings. More than 75% of the information we receive about the world around us consists of visual information. The eye is often compared to a camera. Each gathers light and then transforms that light into a "picture

and unfamiliar exercise‚ particularly which involves eccentric muscle actions can cause muscle damage and lead to delayed-onset muscle soreness (DOMS)‚ which may impair performance. This is due to the high force features of eccentric contraction (Starbuck & Eston‚ 2011). It can also cause muscle shortening‚ swelling and loss of strength in the muscles. Injuries commonly occur during eccentric loading of the muscle; that is‚ when the muscle is contracting while it is lengthening. (LaStayo‚ et al.‚ 2003)

A Tormented Toad Once upon a time‚ a little frog was trapped in the bottom of a well for 100 years‚ torn between returning to his former state of royalty‚ or remaining a lowly frog; but upon closer inspection‚ this fairy tale offers more than the moans of a tormented toad. It gives readers insight to a common fear that many Christians are subjected to. Within the poem “The Frog Prince‚” Stevie Smith uses the word “disenchanted” to refer to humans being freed from their mortal bodies and moving

people refer to the poison frog as the “jewels of the Rainforest‚” because of their peculiar colors‚ but beware these frogs can be very deadly. Their main habitat is the bottom of tropical rainforests‚ yet the some live high in the canopy and never come down. They have amazingly bright colors and fantastic patterns to warn other rainforest animals that they are poisonous‚ but occasionally they are swallowed‚ and the consumer might die depending on the type of poison frog. Their colors range from blue

Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS
