What are the 4 characteristics of smooth muscle tissue cells?

Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control.

What are the characteristics of smooth muscle tissue?

Smooth muscle contains thick and thin filaments that do not arrange into sarcomeres, resulting in a non-striated pattern. On microscopic examination, it appears homogenous. Smooth muscle cytoplasm contains large amounts of actin and myosin. Actin and myosin act as the main proteins involved in muscle contraction.

What are the three characteristics of smooth muscle cells?

Visceral Muscle

Four characteristics define smooth muscle tissue cells: they are involuntarily controlled, not striated, not branched, and singly nucleated.

What are the characteristics of smooth muscle quizlet?

Match
  • Single nucleus per cell.
  • No branches.
  • No cross striations (no sarcomeres)
  • Slow, rhythmic, prolonged contractions of visceral organs.
  • Involuntary movement.

What is the function of smooth muscle cells?

Smooth muscle cells are quite heterogeneous, depending on the organ system in which they serve their function. Their major role is to control the diameter, wall movement, and wall stiffness of hollow organs like the vascular, bronchial, gastrointestinal or urogenital system as well as the uterus.

What are the 5 characteristics of muscle tissue?

Terms in this set (5)
  • Excitability- can be stimulated by chemical signals, nerves and stretch.
  • Conductivity- the signal for a muscle to contract is spread from the point of stimulation throughout the entire muscle.
  • Contractility- ability of the muscle to shorten.
  • Extensibility- …
  • Elasticity-

Which is not a characteristic of smooth muscle?

Smooth muscles are found in limbs is not the characteristic of smooth muscles. Explanation: Smooth muscles are found in limbs is not the characteristic of smooth muscles. Active or skeleton muscles are located in the limbs, whereas involuntarily muscles are located in the lungs.

What are smooth muscles quizlet?

Smooth muscle is found in the walls of the hollow internal organs, including all blood vessels except the capillaries, the gastrointestinal tract, and the urinary bladder. Smooth muscle is not striated and it is not subject to voluntary control.

What are the characteristics of muscles quizlet?

  • Contractility. when the heart muscle contracts, moving blood through the heart.
  • Excitability. irritability.
  • Excitability. …
  • Extensibility. …
  • Elasticity.

What are the characteristics of muscle tissue quizlet?

Terms in this set (4)
  • Electrical excitability (conductivity) Muscle fibers respond to stimuli by conducting electrical impulses called action potentials.
  • Contractility. Muscle contracts and becomes shorter and thicker. …
  • Extensibility. Ability to extend (stretch) without being demaged.
  • Elasticity.

What is the function of smooth muscle quizlet?

Explanation: Smooth muscle cells are responsible for involuntary movements like regulation of blood flow through vital organs and movement of materials along digestive and urinary passageways.

What are the 4 main characteristics of muscle tissue?

All muscle tissues have 4 characteristics in common:
  • excitability.
  • contractility.
  • extensibility – they can be stretched.
  • elasticity – they return to normal length after stretching.

What are the 4 functional characteristics of muscle tissue?

Excitability – ability to respond to stimuli; Contractibility – ability to contract; Extensibility – ability of a muscle to be stretched without tearing; Elasticity – ability to return to its normal shape.

What are the characteristics of each muscle type?

Skeletal muscle is voluntary and striated, cardiac muscle is involuntary and straited and smooth muscle is involuntary and non-striated.

Which description of smooth muscle tissue is most accurate?

Which description of smooth muscle tissue is most accurate? This tissue type, in addition to certain muscle tissues, is capable of generating electrical impulses.
