Question

Difference between crista and macula

Answer 1

Each duct has a terminal enlargement called an ampulla which contains a crista ampullaris, a small crest bearing sensory receptor cells. Vestibular Apparatus: ... 2) macula of the saccule — the sensory spot in the wall of the saccule; it detects linear acceleration in the vertical plane (up and down).

Answer 2

Difference between crista and macula:

Crista:

• Crista is a sensory organ of 'rotation'.
• It is located in the 'ampullae' of the semi-circular canals of the inner ears. There are actually 3 pairs of crista in the inner ear.
• The function of crista is to sense the 'angular acceleration' and 'deceleration'.

Macula:

• Macula lies in the saccule and is the 'sensory spot' in the walls of the saccule.
• Its function is to detect linear acceleration in a vertical plane.
• Macula is basically hair cells.
