What is the basic functional unit of a myofibril?
sarcomere
What is one of the functional units of a myofibril?
sarcomere
What is the muscular structure?
The myofibril is the basic muscle cell, within which is the sarcomere, the basic unit of muscle contraction.
Myofibrils consist of contractile proteins called?
Myofilaments Two types: actin (thin filament) & myosin (thick filament)
What is a contractible unit of muscle?
Sarcomere
What is the segment of a myofibril between two Z-lines?
sarcomereThe contractile units are called sarcomeres.
What is a myofibril?
A myofibril is a bundle of contractile filaments (myofilaments), 1-2 μm in diameter, that are arranged in parallel groups in the cytoplasm of striated muscle cells.
What is the contractile unit within a myofibril called?
The sarcomere is the contractile unit. It is the space between two Z discs that contains one group of myosin fillaments and two groups of actin fillaments, one group on each end of the myosin fillaments. Z discs join sarcomeres together end-to-end to form myofibrils. A group of myofibrils surrounded by the sarcolema makes up a muscle fiber.
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 a sacromere?
The sarcomere is the smallest contractile unit of muscle.
What is the smallest individual unit of a contractile tissue called?
a cell
Smallest contractile unit individual muscle fibers?
sarcomere
