Physiology Flashcards
Frontal Lobe
thinking, emotions, problem solving, speech, movement (front of brain)
Parietal Lobe
touch, pressure, temp, and pain. (top/middle of brain)
Temporal Lobe
hearing and memory (sides of brain)
Occipital Lobe
vision (back of brain)
Cerebellum
motor control coordination and learning between spinal cord and other parts of brain. damage does not cause paralysis, but disorders instead (below occipital lobe)
Outer ear
Cup like protrusion from head to direct sounds to the inner ear, via small bones in the middle ear.
Inner ear
Spiral shaped chamber covered in nerves that receive vibrations and send signals to the brain via the auditory nerve.
Contains cochlea and semicircular canals.
Brain uses input from Outer and Inner ears to…
determine direction and distance of sounds.
Viscous fluid and particles in 3 inner ear canals are responsible for…
Balance, spatial orientation. Movement of these things helps brain determine motion and acceleration.
Human ear can perceive frequencies between…
16 cycles per second (deep bass) and 28,000 cycles per second (high pitch).
Perfect pitch
the ability to map a tone precisely on the musical scale without reference to an external standard.
Estimated less than 1 in 10,000 people have perfect pitch.
Retina
Back of eye, covered with 2 types of cells (cones and rods) for peripheral and night vision, and distinguishing colors and light sources.
Cone cells
sensitive to color
Rod cells
sensitive to light
Optic nerve
Connects eye to brain. Connection point is a blind spot.
