What are the three types of muscle tissue?
skeletal, cardiac, smooth
which type of muscle….fibers are long, cylindrical, and multinucleated. Attached to bones and responsible for body movements.
skeletal muscle
which type of muscle…. cells are branched, have a single central nucleus, and are striated. Found only in the heart.
cardiac muscle
which type of muscle… fibers are spindle-shaped, have a single central nucleus, and lack striations, giving them a smooth appearance. Found in the walls of hollow organs such as the intestines, blood vessels, bladder, and uterus.
smooth muscle
Excitability, Contractility, Extensibility, Elasticity, Voluntary Control,
Striated Appearance, Multinucleated Cells
the properties of skeletal muscle
What is the function of skeletal muscle?
Produce movement, maintain posture, support, generate heat, storage and movement of materials
What are the three layers of connective tissue found in muscle?
Epimysium, Perimysium, Endomysium
What does Epimysium surround, i.e., fascicles, muscles?
surrounds entire “muscle” divides individual muscle
What does Perimysium surround, i.e., fascicles, muscles?
surrounds fascicles
What does Endomysium surround, i.e., fascicles, muscles?
surrounds individual muscle fibers within the fascicles
the basic functional within muscle cells. This unit is distinctive in some types of muscle tissue. It can be observed on microscope slides due to the striated nature of both skeletal muscle and cardiac muscle.
sarcomere
What are examples of circular muscles?
orbicularis oris, orbicularis oculi
What are examples of convergent
muscles?
pectoralis muscle
What are examples of parallel
muscles?
sartorius muscles, biceps brachii
What are examples of pennate
muscles?
rectus femoris, deltoid, tibialis anterior, dorsal interossei
a substance or agent that enhances the effect of another substance or
Agent when combined.
synergist
is a molecule that can bind to the receptor but does not trigger a cellular response.
antagonist
