Microtubules are primarily involved in maintaining cell shape, providing structural support, and facilitating intracellular transport rather than directly enabling contraction and movement. They play a crucial role in the organization of the mitotic spindle during cell division and are part of the cytoskeleton. Cell movement is predominantly driven by actin filaments and myosin interactions, which are responsible for muscle contraction and amoeboid movement. Thus, while microtubules contribute to cellular dynamics, they do not directly facilitate contraction.
The cells that transmit sensory messages are called nerve cells or neurons. Muscle cells, also known as myocytes, are responsible for contraction and movement.
Non-contractile refers to tissues or structures that cannot undergo contraction, such as certain cells, like nerve cells, or non-muscle tissues like bone or cartilage. These tissues do not have the ability to actively generate force or movement through contraction.
The main type of cell found in muscle tissue in your arm is the muscle cell, also known as a muscle fiber. These cells contain contractile proteins that allow for movement and contraction of the muscle.
Animals have different forms of specialization that allow them to have muscle cells and other cells that aid movement.
Permeable cells are cells that allow the movement of certain substances across their membrane. Examples include plant cells, red blood cells, and white blood cells. These cells have specialized structures that facilitate the movement of molecules in and out of the cell.

Muscle tissue consists of cells that are highly specialized for the function of contraction. These cells contain proteins that allow them to generate force and movement. Muscle tissue can be classified into three types: skeletal, cardiac, and smooth muscle, each with unique properties related to their specific functions.
Microtubules are in all Eukaryotic cells.
Locomotion , movement , contraction etc .
Yes, both plant and animal cells have microtubules.
True
The cytoskeleton is a series of proteins that are intercellular and which help with the support, shape and movement of cells. The three main componemnts that the cytoskeleton is composed of are microfilaments, intermediate filaments and microtubles.
It's muscle cells that carry out the movement, and nerve cells that control the contraction of the muscle cells. Bone cells are also involved indirectly, by providing the framework for the muscles to attach to.
The intercalated discs are specialized structures in cardiac muscle that allow for uniform contraction. They contain gap junctions, which allow for rapid electrical communication between cells, ensuring synchronous contraction of the heart muscle. Additionally, desmosomes in the intercalated discs help to physically link neighboring cardiac muscle cells, allowing for force transmission during contraction.

Non-contractile refers to tissues or structures that cannot undergo contraction, such as certain cells, like nerve cells, or non-muscle tissues like bone or cartilage. These tissues do not have the ability to actively generate force or movement through contraction.
T-tubules are structures in muscle cells that help transmit electrical signals for muscle contraction. They allow for the rapid spread of these signals throughout the cell, ensuring coordinated muscle fiber contraction.
