Diagram of the Structure of a Muscle Cell (also called a muscle fibre). The structure of a muscle cell can be explained using a diagram labelling muscle filaments, myofibrils, sarcoplasm, cell nuclei (nuclei is the plural word for the singular nucleus), sarcolemma, and the fascicle of which the muscle fibre is part. The structure of muscle fibers is included in courses in human biology and ...

Muscle Cell Definition. A muscle cell, known technically as a myocyte, is a specialized animal cell which can shorten its length using a series of motor proteins specially arranged within the cell. While several associated proteins help, actin and myosin form thick and thin filaments which slide past each other to contract small units of a ...
Muscle cells, commonly known as myocytes, are the cells that make up muscle tissue.There are 3 types of muscle cells in the human body; cardiac, skeletal, and smooth. Cardiac and skeletal myocytes are sometimes referred to as muscle fibers due to their long and fibrous shape.
Muscle cells are in most ways identical to any other animal cell. The only major difference is that muscle cells, or myocytes contain many more mitochondria. This is because myocytes need more ...

There are more mitochondria in cells that have to perform lots of work, for example- your leg muscle cells, heart muscle cells etc. Other cells need less energy to do their work and have less mitochondria. ... Some vesicles deliver materials to parts of the cell and others transport materials outside the cell in a process called exocytosis.
Muscle cells are highly specialized, each optimally designed to perform its required function, and there is variation amongst muscle cells within each category. There are three different types of muscle cells in the human body: skeletal, smooth and cardiac.
The second muscle group, which controls many of the human involuntary movements like breathing is called a smooth muscle or nonstriated cell. The third muscle cell group is the group that controls the beating of the heart, the cardiac muscle cell. Smooth Muscle Cells and Hollow Spaces
