Each taste bud contains only one taste cell.

Taste cells are neurons that directly transmit signals to the brain.

Taste cells make up the majority of the cells in the tongue’s epithelium.

Taste cells form synapses with gustatory afferent axons.

have no hydrophobic portions

are completely embedded within the lipid bilayer

Overlapping stimulation of cone types allows perception of intermediate hues.

Rods contain three types of opsins for colour detection.

Colour vision is processed entirely in the retina without brain involvement.

Each cone cell responds to all wavelengths equally.

MS increases the speed of nerve impulse conduction.

MS is a result of Schwann cell dysfunction in the peripheral nervous system.

MS is caused by the destruction of the myelin sheath in the central nervous system.

MS primarily affects skeletal muscles directly, causing them to degenerate.
