Skeletal Muscle Physiology Activity 1 1. Skeletal muscle fiber- long‚ cylindrical cell with multiple oval nuclei arranged just beneath the sarcolemma Motor unit- all of the muscle cells controlled by a single motor neuron Skeletal muscle twitch- a single stimulus-contraction-relaxation cycle in a skeletal muscle Electrical stimulus- uses an electrical current to cause a single muscle or a group of muscles to contract Latent period- the time between the stimulation of a muscle and the start

HB105: Introductory Physiology The Action of Enzymes Introduction An enzyme is located in all living cells‚ and is a complex protein molecules. These protein based molecule act as a catalyst. This is a compound that aids chemical reactions without its own structure and state being changed during the process. Catalysts speed up chemical reactions‚ changing substrates into specific produce. Without these enzymes life would not exist. Enzymes are fundamental to all living things as they speed up

Vanessa Yang Smith Period 6 Biology HP 17 March 2014 Biology Study Guide: Unit 6 Physiology III Benchmark 1. Homeostasis maintains and keeps a balance of an organism’s internal environment. 2. The body maintains homeostasis by the feedback inhibition‚ in which a stimulus produces a response that opposes the original stimulus. 3. The axon terminal is the nerve ending. The nodes speed up the message. The myelin sheath is an insulating membrane. The axon carries impulses away from the cell body

How Energy is used in the Body (M1) We get chemical energy from food we eat and oxygen that we breathe –we need this to get energy into a usable form to be used by the cells Glucose + Oxygen ----------------> Carbon Dioxide + Water (C6H12O6) (O2) Metabolism (CO2) (H2O) (1C6H12O6) (6O2) In Cells (6CO2) (6H20) Metabolism is the process of getting chemical energy from larger molecules in food and breaking them down into smaller
