Flashcards

Iris

The colored part of the eye that controls the amount of light entering the pupil.

Semicircular canals

Three fluid-filled loops in the inner ear that detect head movement and help maintain balance.

Lens

The transparent, flexible structure behind the pupil that focuses light onto the retina.

Medulla oblongata

The lower part of the brainstem responsible for essential bodily functions like breathing and heart rate.

Study Notes

Eye and Vision

  • The iris controls the amount of light entering the eye by adjusting the size of the pupil.
  • The lens focuses light onto the retina, enabling clear vision at varying distances.

Ear and Balance

  • The vestibular system, which includes the semi-circular canals, is responsible for maintaining balance and equilibrium.

Nervous System Functions

  • The medulla oblongata regulates vital autonomic functions such as breathing, heart rate, and blood pressure.
  • The myelin sheath insulates nerve fibers, increasing the speed of electrical impulses and ensuring efficient communication within the nervous system.

Brain and Emotions

  • The limbic system, particularly the amygdala and hippocampus, is crucial for processing emotions and forming memories.
