Smooth Muscles: Properties and Factors | Humans | Biology

In this article we will discuss about the properties and factors affecting the activity of smooth muscles in human body. Properties of Smooth Muscles: Broadly speaking, properties of the smooth muscle are same as those of the skeletal muscle, with the following differences: i. Excitability and Contractility: Smooth muscle is less excitable. Contraction is slow, and worm-like. All the peri­ods [...]

Skeletal Muscles: Properties and Contractions | Humans | Biology

In this article we will discuss about:- 1. Composition of Skeletal Muscles 2. Properties of Skeletal Muscles 3. Vascular Arrangement 4. Rate of Blood Flow 5. Control of Skeletal Muscle Blood Flow 6. Contractions. Composition of Skeletal Muscles: Skeletal Muscles Composition: i. Water—75% ii. Solid-25% Solids: 1. Proteins: 20%. Actin and myosin form about half the total muscle protein. Myosin, [...]

Chronaxie and Rheobase of Various Tissues | Muscles | Humans | Biology

The excitability of different tissues varies widely. Some tissues are highly excitable whereas others are dull. While considering the excitability of a tissue two factors are to be considered: (a) The strength of the current used, and (b) The duration of the current flowing through the tissue. These two factors bear an inverse relation. The stronger the current the lesser [...]
