  2. Neurotransmission - Wikipedia

    en.wikipedia.org/wiki/Neurotransmission

    Storage of the neurotransmitter in storage granules or vesicles in the axon terminal. Calcium enters the axon terminal during an action potential, causing release of the neurotransmitter into the synaptic cleft. After its release, the transmitter binds to and activates a receptor in the postsynaptic membrane. Deactivation of the neurotransmitter.

  3. Neurotransmitter - Wikipedia

    en.wikipedia.org/wiki/Neurotransmitter

    Acetylcholine was the first neurotransmitter discovered in the peripheral and central nervous systems. It activates skeletal muscles in the somatic nervous system and may either excite or inhibit internal organs in the autonomic system. [17] It is main neurotransmitter at the neuromuscular junction connecting motor

  4. Neuromuscular junction - Wikipedia

    en.wikipedia.org/wiki/Neuromuscular_junction

    A neuromuscular junction (or myoneural junction) is a chemical synapse between a motor neuron and a muscle fiber. [1] It allows the motor neuron to transmit a signal to the muscle fiber, causing muscle contraction. [2] Muscles require innervation to function—and even just to maintain muscle tone, avoiding atrophy.

  5. Birth control - Wikipedia

    en.wikipedia.org/wiki/Birth_control

    Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent pregnancy. [1] [2] Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. [3]

    en.wikipedia.org/wiki/Combined_oral...

    The combined oral contraceptive pill (COCP), often referred to as the birth control pill or colloquially as "the pill", is a type of birth control that is designed to be taken orally by women. It is the oral form of combined hormonal contraception .

  7. Oral contraceptive pill - Wikipedia

    en.wikipedia.org/wiki/Oral_contraceptive_pill

    Oral contraceptives, abbreviated OCPs, also known as birth control pills, are medications taken by mouth for the purpose of birth control. The introduction of the birth control pill ("the Pill") in 1960 revolutionized the options for contraception, sparking vibrant discussion in the scientific and social science literature and in the media.

  8. Chemical synapse - Wikipedia

    en.wikipedia.org/wiki/Chemical_synapse

    The neurotransmitter binds to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft. Chemical synapses are biological junctions through which neurons ' signals can be sent to each other and to non-neuronal cells such as those in muscles or glands .

  9. Neuroeffector junction - Wikipedia

    en.wikipedia.org/wiki/Neuroeffector_junction

    A neuroeffector junction is a site where a motor neuron releases a neurotransmitter to affect a target—non-neuronal—cell. This junction functions like a synapse . However, unlike most neurons, somatic efferent motor neurons innervate skeletal muscle, and are always excitatory.
