What is a contractile response of a single muscle fiber to a single muscle impulse called?
The contractile response of a single muscle fiber to a single muscle impulse is called a "twitch." A twitch consists of a brief contraction followed by relaxation, and it can be divided into three phases: the latent period, contraction phase, and relaxation phase. The characteristics of a twitch, such as its duration and force, can vary depending on the type of muscle fiber involved.

What does contractile impulse mean?
Contractile impulse refers to the electrical signal that initiates contraction in muscle cells. In cardiac muscle, this impulse originates from the sinoatrial (SA) node, propagating through the heart to coordinate rhythmic contractions. In skeletal muscle, it results from signals transmitted by motor neurons. Overall, contractile impulses are crucial for the effective functioning of both cardiac and skeletal muscles.
What is the contractile tissue of the body?
There is no such thing. Were something non-contractile, it would cease to be called a muscle. You probably meant "What is a contractile muscle structure?" or something similar. There are many such answered questions on here.
What takes up most of a muscles cell volume and is the contractile component of a muscle cell?
The component that takes up most of a muscle cell's volume and is responsible for contraction is the myofibrils. These structures are composed of repeating units called sarcomeres, which contain the contractile proteins actin and myosin. When stimulated by a nerve impulse, these proteins interact to produce muscle contraction. Thus, myofibrils are essential for the muscle's ability to generate force and movement.
What is non contractile muscle structures called?
series-elastic elements
Contractile and non-contractile heart muscles?
The non-contractile element are skeletal muscles that don't contract such as Epimysium,Perimysium and, Endomysium. Contractile muscle contract as a whole muscle instead of single bundles of muscle fibers
What are the longitudunal bundles in the cytoplasm of a skeletal muscle cell called?
the so called longitudinal bundles in the cytoplasm of a skeletal muscle are actually the muscle contractile proteins, namely actin and myosin.
What are the 3 structural components of a neuromuscular response?
The three structural components of a neuromuscular response are the motor neuron, the neuromuscular junction, and the muscle fiber. The motor neuron transmits signals from the brain or spinal cord to the muscle, the neuromuscular junction is where the motor neuron and muscle fiber meet and communicate, and the muscle fiber is the contractile tissue that generates force in response to nerve signals.
What is a contractible unit of muscle?
Sarcomere
The movable part of a muscle is?
The sarcomere is the contractile unit of a muscle fiber.
Does cardiac muscle have neurogenic contractile ability?
No, it has myogenic contractile ability. Source: Physiology book

muscles
What contractile elements are in muscle cells?
sacromere
