With which type of equilibrium are the maculae mainly concerned?

Explanation

**Step-by-Step Solution:**

1. **Understanding Maculae**: The maculae are specialized sensory structures located in the vestibular system of the inner ear. They are part of the otolith organs, which include the utricle and saccule.

2. **Function of Maculae**: The primary function of the maculae is to detect changes in the position of the head in relation to gravity. This is crucial for maintaining balance and spatial orientation.

3. **Equilibrium Types**: There are two main types of equilibrium: static equilibrium and dynamic equilibrium. Static equilibrium refers to the body's ability to maintain balance when stationary, while dynamic equilibrium involves balance during movement.
