The 29 pages that link to Smooth muscle, each with the reason it gives.

• Skeletal muscleCompared with: Its nonstriated structure and involuntary control contrast with skeletal muscle's typical organization.

• Neuromuscular junctionCompared with: Smooth muscle is often controlled through diffuse autonomic signaling rather than a skeletal-type end plate.

• Muscle contractionBroader topic: It generates sustained force using actin and myosin without striated organization.

• Muscarinic acetylcholine receptorRelated: M3 receptor activation contracts smooth muscle in several organs.

• PeristalsisNarrower topic: Its coordinated contractions form the muscular basis of digestive peristalsis.

• OxytocinRelated: Oxytocin receptors on uterine smooth muscle help generate contractions.

• Cardiac muscleCompared with: Its lack of sarcomeric striations distinguishes it from cardiac muscle.

• EsophagusRelated: Smooth muscle in the lower esophagus contributes to propulsion and sphincter control.

• SarcomereCompared with: Its contraction uses actin and myosin without the repeating banded architecture seen here.

• Vascular smooth muscleNarrower topic: Vascular smooth muscle is the smooth-muscle tissue specialized for blood vessels.

• Excitation-contraction couplingCompared with: Its electrical signals regulate contraction through calcium–calmodulin and myosin phosphorylation, not troponin.

• Somatic nervous systemCompared with: It is generally controlled by autonomic pathways, not somatic motor neurons.

• ProstateRelated: Smooth muscle in the prostate contracts during emission of prostatic secretions.

• Sarcoplasmic reticulumCompared with: Its calcium regulation relies less on the highly organized reticulum of striated muscle.

• Vas deferensRelated: Its thick layers form the contractile wall of the vas deferens.

• Uterine contractionNarrower topic: Uterine contractions are a specialized activity of smooth muscle.

• ErectionRelated: Relaxation of smooth muscle in penile arteries and erectile tissue permits engorgement.

• MuscleBroader topic: It moves substances and regulates the diameter of internal passages.

• MyofibrilCompared with: Smooth muscle contracts without the organized myofibrils characteristic of striated muscle.

• HyoscyamineRelated: Muscarinic blockade relaxes smooth muscle and helps relieve spasms.

• Muscular systemBroader topic: It moves materials through organs and regulates the diameter of vessels.

• PapaverineNarrower topic: Papaverine acts on this muscle type to reduce contraction.

• LymphangioleiomyomatosisNarrower topic: LAM cells resemble smooth muscle cells, though they have distinctive abnormal growth behavior.

• Amyl nitriteNarrower topic: Relaxation of vascular smooth muscle produces amyl nitrite’s characteristic drop in vascular resistance.

• MyologyBroader topic: It extends myology beyond muscles that move the skeleton.

• AtonyBroader topic: Atony in this muscle type impairs the normal contraction of hollow organs.

• Human musculoskeletal systemCompared with: Unlike skeletal muscle, it does not directly pull on bones to produce movement.

• Muscle cellNarrower topic: Its individual cells contract without the sarcomere pattern seen in striated muscle.

• VisceraRelated: Its contractions move contents through many hollow viscera.
