Where troponin is found?
Troponin is one of the intracellular proteins found primarily in skeletal muscle fibers, where it is part of the contractile proteins.
In the skeletal muscle what is a Z-disk or Z line?
Z-disks or Z-lines are the points of contraction for contractile proteins. They provide structural support for the transmission of force when the muscle fibers are activated to shorten.
Animal tissue predominantly of contractile cells?
muscle
What special features of muscle cell?
Its contractile ability.
Do skeletal muscle fibers contain sarcomeres whereas smooth muscle fibers do not?
true
What is the contractile organelle of skeletal muscle fibers is?
myofibrils
What is Smallest contractile units of a muscle?
Sarcomere
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 is a sacromere?
The sarcomere is the smallest contractile unit of muscle.
What is the smallest contractile unit of the muscle fiber?
sarcomere
What is the fundamental functional muscle fiber's unit of contraction?
The smallest contractile unit of a muscle fiber is the sarcomere.It is composed of contractile myofilaments known as actin and myosin.
What is the smallest structure in a muscle?
Muscles always contract entirely i.e. every part of the muscle which contains myosin and actin (contractile proteins) is able to contract and does contract almost simultaneously.
Name four factors that influence contractile force and two that influence velocity and duration of contraction?
The four factors that influence contractile force are the number of muscle fibers stimulated, the relative size of the fibers, the frequency of stimulation and the degree of muscle stretch. Factors that influence the velocity and duration of contraction are the muscle fiber type, load and recruitment.
How is cardiac muscle similar to stomach smooth muscle?
Cardiac muscle is similar to smooth muscle in that both are involuntary. Cardiac muscle is similar to skeletal muscle because they are both striated.
Does endomysium separate individual muscle fibers?
True
Where troponin is found?
Troponin is one of the intracellular proteins found primarily in skeletal muscle fibers, where it is part of the contractile proteins.
Individual muscle cells are called?
muscle fibre
