What is muscle treppe?
•Increased contraction in response to multiple stimuli of same strength
What are two body processes that would change in response to an increase in muscle activity?
That would be increased respiration and increased oxidation. .
What is the term used to describe the degree to which an individual muscle will lengthen?
The term used to describe the degree to which an individual muscle will lengthen is "compliance". Compliance refers to the ability of a muscle to stretch or lengthen in response to an external force or load.
How is the all-or-none response related to the strength of a muscle contraction?
The all-or-none response means that a muscle fiber contracts fully or not at all in response to a stimulus. The strength of a muscle contraction is determined by the number of muscle fibers that are recruited to contract, rather than the degree of contraction of individual muscle fibers. Therefore, the all-or-none response influences the overall strength of a muscle contraction by determining how many muscle fibers are activated.
What is pyridostigmine bromide?
Pyridostigmine bromide is a medication used to treat myasthenia gravis, a neuromuscular disease that causes muscle weakness and fatigue. It works by improving communication between nerve cells and muscles, leading to increased muscle strength and function. It is usually taken orally and the dosage is adjusted based on individual response and tolerability.
What action does an organ undergo to best describe the term hypertrophy?
Hypertrophy refers to the increase in size of an organ or tissue due to an increase in the size of its individual cells. This occurs in response to increased workload or stimulation, such as regular exercise causing muscle hypertrophy.
What happens to graded muscle response to increased stimulus intensity?
As the stimulus intensity increases, the graded muscle response also increases in strength. This phenomenon is known as the principle of recruitment, where motor units are activated in a progressive manner based on the intensity of the stimulus. This allows for fine control over muscle force output.
Richmond lang effect is produced by?
The Richmond Lang effect is produced by the increased firing rate of muscle spindles that occurs when a muscle is subjected to a sudden stretch. This reflex response helps to protect the muscle from potential injury by quickly contracting in response to stretching.
What is an increasingly stronger contractions owing to increased stimulus strength known as?
The phenomenon of increasingly stronger contractions owing to increased stimulus strength is called recruitment. It involves activating more muscle fibers within a muscle to generate greater force in response to a stronger stimulus.
Why during fight or flight do your muscles become tense?
During the fight or flight response, the body releases stress hormones like adrenaline, which increase muscle tension to prepare for a physical response. This increased muscle tension helps to improve strength and speed in either fighting or fleeing from a threat.
What does hypertension do to the heart?
Hypertension is a condition of increased blood pressure. This increased pressure on the heart causes eventual weakening of the heart muscle, and places the individual at greater risk of eventual heart faillure.
What causes arterioles to dilate in response to increased sympathetic tone?
Increased sympathetic tone leads to the release of norepinephrine, which binds to alpha-1 adrenergic receptors on arteriolar smooth muscle. This binding initiates a signaling cascade that ultimately results in the relaxation of the smooth muscle, causing the arterioles to dilate.
