The tongue
Skeletal muscle.
The chemical used at the junction with a skeletal muscle is acetylcholine (ACh). It is released from the motor neuron at the neuromuscular junction and binds to receptors on the muscle fiber's membrane, triggering muscle contraction. This process is essential for voluntary movement and is part of the overall neuromuscular signaling mechanism.
skeletal smooth muscle neuron
Smooth muscle tissue has a single nucleus in each cell :)
Going from superficial to deep in the muscle:Each skeletal muscle is covered by a fourth, very tough fibrous layer of CT called deep fascia.The deep fascia may extend past the length of the muscle (tendon or aponeurosis), and attach that muscle to a bone, cartilage or muscle. Each skeletal muscle is covered by a third layer of dense, fibrous CT called epimysium.Many fascicles are bundled together to form a skeletal muscle.Many muscle fibers are bundled together into groups called fascicles. Each fascicle is wrapped in a second layer of CT made of collagen called perimysium.Each muscle fiber (cell) is wrapped in a thin layer called endomysium.
The tongue is mostly muscle covered by a mucous membrane. The tongue also has the taste buds.
An ulcer is not a type of muscle. It is an open sore on a mucous membrane like the stomach wall or on the skin.
This is the fascia, which is actually composed of three separate levels. There is one layer that wraps around each muscle fiber, another layer that wraps around each muscle bundle and then a final layer that wraps around the whole muscle.
If you think about it, skeletal muscle are muscles that connect bones. So wherever you have bone, it is covered with skeletal muscle. Muscles do not connect bones. Muscles are the source for movement and protection for bones.
epimysium in the skeletal muscle, plasma membrane of the muscle cell is not sarcoplasm but rather sarcolemma

The lips are folds of skeletal muscle covered with transparent epithelium.
A skeletal muscle.
No, nipples are not considered mucous membranes. Mucous membranes line various body cavities and organs that are exposed to the external environment, such as the mouth, nose, and digestive tract, and secrete mucus to protect against infection. Nipples are composed of skin, glandular tissue, muscle, and connective tissue, but do not secrete mucus.
