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 else can I help you with?
What is one of the functional units of a myofibril?
sarcomere
What is a contractible unit of muscle?
Sarcomere
What is the muscular structure?
The myofibril is the basic muscle cell, within which is the sarcomere, the basic unit of muscle contraction.
What is the smallest individual unit of a contractile tissue called?
a cell
What happens in the sarcomere?
area in the muscle between the two Z discs.
What is the basic functional unit of a myofibril?
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 a sacromere?
The sarcomere is the smallest contractile unit of muscle.
Smallest contractile unit individual muscle fibers?
The smallest contractile unit of individual muscle fibers is called a sarcomere. Sarcomeres are made up of overlapping thick and thin filaments that slide past each other during muscle contraction, generating the force necessary for movement.
What is the smallest contractile unit of the muscle fiber?
sarcomere
The movable part of a muscle is?
The sarcomere is the contractile unit of a muscle fiber.
What is a series of sarcomeres linked together known as?
A series of sarcomeres linked together is known as a myofibril, which is the basic functional unit of a muscle cell. The myofibrils run parallel to each other within muscle fibers and are responsible for muscle contraction.
