One of the functional units of a myofibril is the sarcomere. Sarcomeres are the basic contractile units of muscle cells and are responsible for muscle contractions by sliding the actin and myosin filaments past each other.
The smallest functional unit in a myofibril is a sarcomere.
A sarcomere is composed of thin (actin) and thick (myosin) filaments. Actin slides past myosin when the muscle contracts.

Where are the nephron units located in the kidney?
Nephron units are located in the kidney cortex. They are the functional units responsible for filtering blood and regulating the electrolyte balance and fluid volume in the body. Each kidney contains thousands of nephron units.
The functional units of DNA that contain the instructions for making one or more proteins are?
Genes are the functional units of DNA that contain the instructions for making one or more proteins. Each gene consists of a specific sequence of nucleotides that encode the information needed to produce a particular protein.
What is the functional unit of a organ?
the unit impulse function g(t)
What are the smallest units that carry on the functions of life?
The smallest units that carry out the functions of life are cells. Cells are the basic structural and functional units of all living organisms. They perform essential functions such as energy production, protein synthesis, and replication.
Does the cortex contain nephrons?
No, the cortex does not contain nephrons. Nephrons are the functional units of the kidneys and are predominantly located in the renal cortex and renal medulla.
What is one of the functional units of a myrofibril?
One of the functional units of a myofibril is the sarcomere. The word sarcomere comes from the Greek words sarx, meaning flesh, and meros, meaning part.
What is the basic functional unit of a myofibril?
sarcomere
What are tiny contractile units linked together on a myofibril?
Sarcomeres are the tiny contractile units linked together on a myofibril. They are the functional units of muscle tissue and are responsible for muscle contractions. Sarcomeres consist of thick and thin filaments made of proteins that slide past each other during muscle contraction.
What are Myofibrils composed primarily of?
Myofibrils are primarily composed of proteins called actin and myosin. These proteins are arranged in a repeating pattern along the length of the myofibril, forming the sarcomeres, which are the functional units responsible for muscle contraction.
What is the segment of a myofibril between two Z-lines?
sarcomereThe contractile units are called sarcomeres.
Muscle cells contain contractible units called?
Myofibril, composed of actin and myosin.
What do the renal pyramids contain?
One million functional units
What are the functional units of the units called?
They are genes.
The smallest functional unit of the muscle fiber?
The smallest functional unit of a muscle fiber is the sarcomere. Sarcomeres are composed of actin and myosin filaments arranged in a repeating pattern, allowing for muscle contraction and relaxation to occur. They are responsible for the striated appearance of skeletal muscle under a microscope.
Functional units of lungs?
Alveoli
What repeating units make up a muscle fiber?
sacomeres are a single unit of a muscle fiber multiple sacomeres make up a myofibril
Long filamentous organelle with a banded appearance?
This description matches a structure called a myofibril, which is found in muscle cells. Myofibrils are made up of repeating units called sarcomeres that give them a banded appearance. They are responsible for muscle contractions by interacting with motor proteins.
