anything that we perceived through senses
Sensation
perceived through senses and are interpreted or we give opinions about it
Perception
refer to any objects, events, or situations that elicit a response from an individual.
It can come from both the external environment (like sounds, lights, or social interactions) or internal states (like hunger, thoughts, or emotions).
Stimuli
are specialized cells or structures that detect and respond to stimuli, converting external or internal environmental signals into electrical impulses that can be interpreted by the nervous system.
It let’s us experience sensations
Receptors
refers to the process by which the sensory systems in the body adapt, adjust, or become less responsive to continuous or unchanging stimuli over time in a particular situation. This allows individuals to tune out irrelevant background information and focus on new or more important stimuli.
Ex. Foreigners become used to hot weather in the Philippines after staying for a long time
Sensory Adjustment
Release in sweat and is used for mating in animals.
Study also said that it is an indicator for compatibility in people through genetics
Pheromones
EYES
Focuses light onto the retina by adjusting its shape
Lens
EYES
The small, black circular opening in the center of the iris that controls how much light enters the eye.
Pupil
EYES
The colored part of the eye, controlling the size of the pupil.
Iris
EYES
The clear, watery fluid between the cornea and the lens. It nourishes the lens and cornea and helps maintain intraocular pressure to keep the eye’s shape.
The cavity of the eyes
Aqueous Humor
EYES
Contains receptors of the eyes. It is the thin layer of tissue lining the back of the eye that contains light-sensitive cells.
Retina
EYES
Within Retina that is responsible for color vision and work best in bright light.
Lack of it can lead to color blindness
Cone
EYES
Within Retina that is responsible for vision in low light and peripheral vision. (gray, black)
Rods
EYES
Transmits electrical signals from the retina to the brain, where they are processed into visual images. (the receiver of information to the brain)
Optical Nerves
EYE DISEASE
also known as hyperopia
only far objects are clear
the point of focus falls behind the retina, making close-up objects appear blurry
Far Sightedness
EYE DISEASE
also known as myopia
only near objects are clear
is a refractive error that makes far-away objects look blurry.
Nearsightedness
EYE DISEASE
A common vision problem where the eye does not focus light evenly onto the retina, causing blurred or distorted vision at any distance.
Astigmatism
Eye diseases
- Farsightedness
- Nearsightedness
- Astigmatism
PART OF OUTER EAR
The visible part of the ear that helps collect sound waves and directs them into the ear canal.
receiver of sound in the ears
Pinna
PART OF OUTER EAR
A tube-like structure that carries sound from the pinna to the eardrum. It also protects the inner structures by producing earwax.
Ear Canal
PART OF MIDDLE EAR
A thin membrane that vibrates when sound waves hit it. These vibrations are then passed to the middle ear.
Ear Drum
PART OF MIDDLE EAR
The three bones in the ears that serves as the doubling of sound waves.
Hammer
Anvil
Stirrup (smallest bone)
PART OF INNER EAR
Are receptors/stimulus in the ear that are spiral-shaped, fluid-filled structure responsible for converting sound vibrations into electrical signals.
Cochlea
PART OF INNER EAR
Carries electrical signals generated by the cochlea to the brain, where they are interpreted as sound.
Auditory Nerve
