In addition to pain receptors in the brain, other mechanisms that can cause headaches include changes in blood flow, chemical imbalances, muscle tension, and nerve irritation.
The nerves responsible for causing headaches are the trigeminal nerve and the occipital nerve.
High levels of CO2 in the environment can contribute to causing headaches in individuals by reducing the amount of oxygen available for the brain, leading to decreased cognitive function and increased blood flow to compensate, which can result in headaches.
The hormone responsible for causing lactation in breastfeeding mothers is called prolactin.
The hormone responsible for causing milk production in the body is called prolactin.
Nerves play a key role in causing headaches by transmitting pain signals to the brain when there is irritation or inflammation in the head or neck region. This can be triggered by various factors such as stress, muscle tension, or changes in blood flow.

The THC in marijuana attaches to naturally produced cannabinoid receptors in the brain and changes how these receptors process information. The natural regulating mechanisms become blocked and produce an overflow of chemicals, causing the disruptions of regular brain functioning. Areas highly affected by the drug include the cerebellum and basal ganglia. These areas are responsible for movement, coordination, balance and body control. The cognitive system, including the hippocampus and cerebral cortex, are areas responsible for learning, memory and thinking. Cognitive functions are overloaded by THC during marijuana use and create lapses in thought process, time delay and loss of memory.
If you have been experiencing headaches for at least a month then you should see a doctor to find out what is causing them. The stress of worrying could also be causing them.
Neostigmine is a competitive irreversible inhibitor of Acetylcholinesterase (AChE), an enzyme responsible for breaking down acetylcholine (ACh). Myasthenia gravis is caused by the body producing too little ACh receptors. As stimulating the ACh receptors is needed for nervous transmission, the nerve signals cannot be transmitted causing muscle weakness and fatigue. Neostigmine is hence used to inhibit AChE so that less ACh gets broken down. This leads to more ACh binding to the ACh receptors causing muscular contraction.
Adrenaline, also known as epinephrine, can induce cycloplegia by stimulating the adrenergic receptors in the eye, particularly the alpha-adrenergic receptors. When these receptors are activated, they lead to the relaxation of the ciliary muscle, which is responsible for controlling the shape of the lens for focusing. This relaxation results in the inability to accommodate for near vision, thus causing cycloplegia. Additionally, the overall response of the sympathetic nervous system can inhibit the parasympathetic pathways that facilitate accommodation.

The bacteria responsible for causing a fishy odor is called trimethylamine-producing bacteria.
Meissner's corpuscles, Pacinian corpuscles, and Merkel cells are sensory receptors found in the skin, responsible for touch and pressure sensations. Arrector pili muscles are associated with hair follicles and are responsible for causing hair to stand on end in response to cold or fear. Arrector pili muscles are not sensory receptors like the other structures listed.
coz it works on alpha 1 adrenergic receptors in small blood vessels causing vasoconstriction and hence increase blood pressure (contrary to its action on skeletal muscles) it is also working on B2 adrenergic receptors causing bronchodilation
