Week #1 -autotrophs are organisms that harvest light or chemical energy in organic compounds. They self nutrition -heterotrophs are organisms that get complex nutrients from the environment (by eating other organisms) -Fungi are heterotrophs or predators because they are parasitic. Bread mold secretes digestive enzymes to enter the membrane. Same as foot fungus‚ it extends hyphae (fungal branches) into the cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus

Earthworm Smooth Muscle In this experiment‚ contractions of the earthworm gut are measured in an organ bath with a force transducer. The effect of neurotransmitters and ionic concentrations on contraction strength and rate will be investigated. Written by staff of ADInstruments With acknowledgement to: Dr. Stuart I. Cromarty‚ Department of Natural Sciences‚ Assumption College‚ Worcester‚ MA‚ USA. [pic] Background Smooth muscle is one of three muscle fiber types found in animals. Unlike

ABSTRACT: Skeletal muscle is able to repair itself through regeneration. However‚ an injured muscle often does not fully recover its strength because complete muscle regeneration is hindered by the development of fibrosis. Biological approaches to improve muscle healing by enhancing muscle regeneration and reducing the formation of fibrosis are being investigated. Previously‚ we have determined that insulin-like growth factor–1 (IGF-1) can improve muscle regeneration in injured muscle. We also

twitch muscle) and not in type I fibers. It is known to be involved in the efflux of lactate from muscle fibers. MCT1 is different‚ because this MCT is found in type 1 fibers and type IIa fibers. This transporter is the transporter that consumes the lactate. MCT2 is the transporter that helps consume the lactate that is formed at rest and is thought to be in the heart. In the review article Cruz et al. (2012) examined two main areas where lactate consumption occurs the heart and skeletal muscle. In

all this walking and running around we don’t think much of it ‚ other than your muscles felling soar at the end of the day‚ but really there’s more to a muscle then what I thought. For example we’ll use the calf muscle ( gastrocnemius). This muscle is connected to the bone by a tendon which is connected to the epimysium. It then breaks down to the fascicles and finally to the muscle fiber ( cell) inside of the muscle fibers of the myofibril‚ inside of that is the those and thin filements. The thin

When the triceps brachii muscle contracts‚ it produces extension of the arm. 3) Why is the inferior region of the shoulder joint most vulnerable to dislocation? It is most vulnerable to dislocation because it is the most mobile synovial joint. Because of this it is frail and relies only on the surrounding ligaments‚ muscles‚ and tendons for stability. 4) A high school student comes

in the muscles of his limbs. The cramping made his muscles feel like hard knots. The foreman of the crew instructed the young man to drink some salt water he had available and rest a while. 1. What is the cause of the cramping? (2 points) The man was doing hard work in intense heat. This caused him to sweat‚ taking sodium out of his body. Sodium is needed to control muscle contraction. Without the necessary amount of sodium‚ the nervous system isn’t able to send messages to the muscles and calcium
