Wavelength of a sound
the distance between two identical parts of a wave for instance the distance between two peaks or troughs. It determines the pitch of the sound.
Frequency
refers to the number of waves that pass a point in a given amount of time, typically measured in Hertz (Hz). It influences the perceived pitch of the sound.
Amplitude
refers to the height of a sound wave, which determines the loudness or intensity of the sound.
Sound localization
is the ability to determine the origin of a sound in our environment. It relies on differences in the time and intensity of sound reaching each ear.
The place theory
suggests that our perception of pitch is linked to the specific location along the cochlea where sound waves trigger neural impulses.
The frequency theory
is a theory that states our perception of pitch is determined by the frequency of neural impulses traveling up the auditory nerve, which matches the frequency of the sound wave.
The volley theory
is a theory that proposes groups of neurons can fire in a rapid succession, allowing for the perception of higher frequencies of sound than individual neurons can achieve alone.
Sensorineural deafness
is a type of hearing loss caused by damage to the inner ear or the auditory nerve, affecting the ability to transmit sound signals to the brain.
Conductive Deafness
is a type of hearing loss that occurs when sound waves are not efficiently conducted through the outer ear canal to the eardrum and the tiny bones of the middle ear.
Olfactory receptors
specialized nerve cells, when Oder molecules enter the nose they bind with these receptors that triggers a series of chemical reaction, Oder molecules are converted into electrical signals that the brain can interpret
Pheromones
Chemical signals released by an individual that affect the behavior or psychology of other individuals
Unami
also known as savory, it is the taste of amino acid L-glutamate, which are found in food like meat and cheese, so portion
Oleogustus
detects taste, is associated with fats
Supertasters
individuals that have a higher-then-average number of receptors, this allows to experience taste more intensely
Medium tasters
individuals that have an average number of taste receptors, who have a more balanced sensitivity to different tastes
Nonstarters
individuals that have fewer taste receptors, making them less sensitive to certain taste. they may not detect bitter flavors as strongly and might prefer food with stronger flavors
Epidermis
the outside layer of your skin, this creates a barrier to protect a person from a foreign pathogens and gives and individual their skin color
Dermis
consists of two different layers. This is connective tissues that is were your blood vessels and nerve endings are located this is also were you get your sense of touch and pain from.
Hypodermis
Not really skin, rather its a layer of fat that helps insulates an individuals tissue and absorbs shots.
Mechanoreceptors
Are sensory receptors located in the skin that respond to pressure
Thermoreceptors
Are sensory receptors located in the skin that respond to temperature changes
Nociceptors
are located in the dermis, these are pain receptors. they are sensory receptors that detect harmful stimuli, such as extreme temperatures, damage, or chemical irritants
The gate control theory
suggests that the spinal cord contains a logical gate that can either block pain signals or allow them to pass through to the brain
Phantom limp sensation
when an individual experiences pain where the body part they lost used to be
Vestibular sense
when you move your head the fluid inside the semicircular canals moves causing the hair cells in the canal to bend, allowing you to maintain your balance
kinesthesis
This is the sense that provides information about the position and movement of individual body parts
this sensory system allows you to know where your limbs are in space, how they are moving without you having you to consistently looking at them
