SHEET NAME_____________________ LAB 6: Skeletal Muscle Physiology Electrical Stimulation 1. Complete the following statements by filling in your answers on the appropriate lines below. A motor unit consists of a (a) and all the (b) it innervates. Whole muscle contraction is a(n) (c) response. In order for muscles to work in a practical sense‚ (d) is the method used to produce a slow‚ steady increase in muscle force. When we see the slightest evidence of force

Currently‚ frog populations around the world are declining. Due to the nature of their life cycles and physiology‚ frogs are very sensitive to environmental changes. Frogs are born in the water as tadpoles. Frogs move onto land for their adult lives. This makes them vulnerable to changes in aquatic habitat availability. This also makes them vulnerable to changes in terrestrial habitat availability. Their aquatic habitats are drying out‚ in areas that are becoming more prone to drought. Frogs are also

A toad is actually a frog it goes from an egg to a tadpole and at this stage it spends it’s time swimming and growing and it breathes with gills and it looks like a fish. The next stage is a tadpole with legs this is the stage where your fish looking tadpole grows legs and small arms‚ has a longer body and has a more distinct head and tail and it still breathes with gills. The you come to the frog-let stage this frog breathes with lungs but still has some of it’s tail but long arms. Finally you come

relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as metubine‚ would interfere with muscle contraction. Aaron arrived at the hospital with the following symptoms: drooping eyelids; fatigue and weakness of his muscles; and difficulty talking‚ breathing and swallowing. What is his diagnosis? Explain. Answer: There are three different types of muscles in the body which are skeletal‚ cardiac and smooth. Skeletal muscle is voluntarily controlled

Lab 6: Amphibian Muscle Contraction Results: For this experiment‚ Isometric contractions of the gastrocnemius muscle of a frog were analyzed and from this data the latent period‚ twitch‚ motor unit summation‚ tetanus‚ fatigue & mechanical summation were measured. The data was used to quantify the effect of passive tension on the twitch force‚ effect of stimulus intensity on the twitch force‚ effect of stimulus frequency on contractile force of xenopus gastrocnemius muscle. The threshold voltage

Physiology of stomach:- For understanding approaches for gastro retention‚ it is essential to overview gastric physiology and gastric motility. The stomach is situated in the left upper part of the abdominal cavity immediately under the diaphragm. Human stomach has a resting volume of 25-50ml‚ which can distend upto1500ml following a meal. It is divided into 5 anatomical parts: a) Cardia:- First part of the stomach below the esophagus. It contains cardiac spincter‚which is a thin ring of muscle

different than humans. First‚ the lungs in a frog have thin walls and are shaped like balloons. When frogs swim‚ they fill their lungs with air‚ which helps them stay buoyant while swimming. Frogs also do not have diaphragms compared to humans. They only breathe through their nose. They use muscles in their throat sacs to help move the air in‚ and then is pushed to the lungs. During this time‚ their mouth is closed. Body contractions allow the frogs to release carbon dioxide. When us humans breathe
