perception.
Receptors that transmit information to the brain Through sensations
The information gets from the receptors to the central nervous system by traveling from one neuron to another through a process in which neurotransmitters are released at synapsis between the neurons.
There are several different touch sensors in the skin. We can distinguish between blunt and sharp, a pressure, or a light stroke with a wisp of cotton wool. We can distinguish vibrations. Your finger tips and lips are very sensitive, and your back is pretty insensitive.
Necessary conditions for sensation include the presence of sensory receptors in the body, the ability of the brain to receive and process sensory information, and a connection between the sensory receptors and the brain through the nervous system. Without these conditions, sensation would not be possible.
Sentience refers to the ability to perceive and feel sensations, while consciousness is the state of being aware of one's own existence and surroundings. Sentience is more basic and refers to the capacity to experience sensations, while consciousness involves a higher level of self-awareness and understanding.
Sensations and feelings are experienced through the interaction of atoms in our bodies, even though they do not physically touch each other. This interaction occurs through the exchange of energy and signals between atoms, which allows us to perceive and feel things.
When a girl dances, she may experience various sensations between her legs, such as the rhythm and movement of her body, the fabric of her clothing, and the connection with the ground. These sensations can include a sense of freedom, exhilaration, or even physical fatigue, depending on the intensity of the dance. Additionally, the movements might create feelings of empowerment and confidence as she expresses herself through dance.
Gustatory receptors are part of the sense of taste. They are in your mouth. Olfactory receptors are part of the sense of smell. They are in your nose.
It doesn't atropine only acts on muscarinic receptors (it's a competitive antagonist here for ACh), but histamine acts on different receptors (histamine receptors). There is no direct interaction between atropine and histamine receptors
Krause's end bulbs are sensory receptors that detect temperature changes in the skin. They are sensitive to cool temperatures, typically between 10-35 degrees Celsius. When the skin is exposed to a cooler environment, these receptors are activated and send signals to the brain to interpret the sensation of cold.
Feeling sadness in your stomach is a common physical response to emotional distress. When you experience strong emotions like sadness, your body releases stress hormones that can affect your digestive system, leading to sensations of discomfort or pain in your stomach. This connection between emotions and physical sensations is known as the gut-brain axis.
