Single cells ... found only in the muscles that move your eyes.
The smallest contractile unit of a muscle fiber is the sarcomere.It is composed of contractile myofilaments known as actin and myosin.
sarcomere
The motor neuron and the muscle fiber it controls constitute a motor unit. This functional unit is essential to the process of muscle contraction and movement in the body. When the motor neuron sends signals to the muscle fiber, it results in the activation and coordination of muscle fibers to produce movement.
just take a guess of what it is.
The smallest functional andstructural unit of kidney is called as -
muscle fiber
Yes
The smallest structural unit of a protein is the amino acid. The smallest functional unit of a protein is a little ambiguous, because some might consider the amino acid to be functional (after all, some can function as neurotransmitters). Or, some might consider the peptide (di, tri, etc) to be a functional unit. One could argue what exactly is the smallest functional unit of a protein.
A fiber
The unit of alternating light and dark striations between Z lines in a muscle fiber is called a sarcomere. Sarcomeres are the functional units of muscle responsible for muscle contraction and relaxation.
The smallest unit of textile material is a fiber. The length of a fiber is greater than the diameter.
