What does excitability mean?
Definition of excitable 1 : capable of being readily roused into action or a state of excitement or irritability. 2 : capable of being activated by and reacting to stimuli excitable cells.
What is excitability quizlet?
Excitability. Excitability means that muscle responds to stimulation by nerves and hormones, making it possible for the nervous system and, in some muscle types, the endocrine system, to regulate muscle activity.
What does excitability mean in psychology?
n. 1. the tendency of some individuals to be readily aroused to emotional responses.
What does extensibility mean in anatomy?
As shown in Figure 6-1, extensibility is the ability to be stretched or to increase in length, and elasticity is the ability to return to normal length after a stretch. Muscle’s elasticity returns it to normal resting length following a stretch and provides for the smooth transmission of tension from muscle to bone.
What is excitable tissue?
• Tissues which are capable of generation and. transmission of electrochemical impulses along. the membrane. Nerve.
What is excitability of a muscle?
Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched or extended. Elasticity is the ability to a muscle to return to its original length when relaxed.
What is extensibility quizlet?
extensibility. the ability to be stretched or extended. elasticity. the ability to recoil and resume the original resting length.
What does Epimysium mean in anatomy?
The epimysium is the dense connective tissue that surrounds the entire muscle tissue. The epimysium usually contains many bundles (fascicles) of muscle fibers. 2. The perimysium is the connective tissue that surrounds each bundle of muscle fibers.
What is nerve excitability?
Nerve excitability is principally determined by the state of membrane sodium channels, which can be influenced by factors such as drugs or the ionic composition of the extracellular fluids.
What does excitability mean for a muscle tissue?
the ability to respond to a stimulus
Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched or extended. Elasticity is the ability to a muscle to return to its original length when relaxed.
How are muscles excitable?
Muscle cells, like neurons, can be excited chemically, electrically, and mechanically to produce an action potential that is transmitted along their cell membranes. Unlike neurons, they respond to stimuli by activating a contractile mechanism.
What is excitable tissue physiology?
EXCITABILITY – is the ability of tissue to react to the stimulation with change of physiological properties and generation of process of excitation. Excitability of cells and tissues is a basic function of life.
