Muscle is excitable because it can be stimulated in order to cause contraction. Stimulation comes from the nervous system via electric signals/action potential that travels from neuron through axon to muscle tissue.
In-depth Details:
- Neuron sends action potential down its axon
- Once reaching the muscle tissue, the action potential stimulates release of Ach (acetylcholine)
- Ach crosses the synapse and binds to a muscle fiber (cell of muscle tissue),
- This stimulates action potential on the sacrolemma (plasma membrane of muscle cell)
- Action potential travels on the sacrolemma until it reaches a T-tubule
- Action goes down the T-tubule and into the muscle fiber
- This stimulates release of Ca2+ (calcium) from the sarcolemma
- Ca2+ binds with troponin
- Which stimulates tropomyosin to move out of the way so that actin and myosin can interact
- If ATP is available from mitochondria in muscle fiber, cross-bridge cycle occurs
- Contraction of muscle stops when the muscle is no longer stimulated from the nervous system

Two basic tissue types are excitable?
excitable tissue is the tissue that can undergo rapid change in their membrane potential which is important to transport electrical signals. by this they can respond to stimuli. example of excitable tissue is nerves and muscle tissue ( skeletal,cardiac and smooth ) - by einstein jr
What kind of cells are excitable?
Excitable cells, such as neurons and muscle cells, have the ability to generate electrical signals called action potentials in response to stimuli. These cells play a crucial role in transmitting signals within the nervous system and facilitating muscle contractions.
Is bone an example of nerve tissue?
Bone is quite different from nerve tissue. It is not an excitable tissue.
What factors contribute to making a tissue excitable?
Factors that contribute to making a tissue excitable include the presence of ion channels, membrane potential changes, and the ability of the tissue to generate action potentials.
Is nervous a tissue?
No, nervous is an adjective meaning sensitive or excitable.
What muscle contains self excitable cells?
The heart muscle contains self-excitable cells known as pacemaker cells. These cells generate electrical signals that control the heart's rhythm by initiating the contraction of the heart muscle.
What are the Components of muscle tissue in a meat?
skeletal muscle tissue,cardiac muscle tissue smooth muscle tissue
Is the muscle tissue superficial to the epidermal tissue?
Muscle tissue is deep to epidermal tissue. Epidermal tissue is superficial to muscle tissue.
Is red blood cell membrane an excitable tissue?
No, the red blood cell membrane is not an excitable tissue. Excitable tissues are able to generate and conduct electrical impulses, which is not a function of red blood cells. Red blood cells are primarily involved in transporting oxygen and carbon dioxide in the bloodstream.
What are the only two types of cells that have excitable membranes?
The only two types of cells that have excitable membranes are neurons and muscle cells. Neurons transmit electrical signals in the nervous system, while muscle cells generate electrical signals that lead to muscle contraction.
Is smooth tissue a muscle tissue?
Smooth tissue refers to a type of tissue that lacks striation and is typically found in organs like blood vessels and the digestive tract. Muscle tissue encompasses three types: skeletal muscle, cardiac muscle, and smooth muscle. Smooth tissue is a specific type of muscle tissue known as smooth muscle tissue.
What tissue is attached to bone that causes movement?
Muscle Tissue
