Maculae are present in

Options

A. Semicircular canals and utriculus
B. utriculus and lagena
C. Utriculus
D. Utriculus and sacculus

Answer

To determine where maculae are present, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Inner Ear**: The inner ear is divided into two main parts: the cochlea and the vestibular system, which includes the semicircular canals and the vestibule.

2. **Identify the Vestibule**: The vestibule contains the otolith organs, which are crucial for balance. These organs include the utricle and the saccule.

3. **Define Macula**: The macula is a specialized structure located within the utricle and saccule. It consists of sensory receptors that are responsible for detecting static balance (the position of the head relative to gravity).

4. **Analyze the Options**:
- **Semicircular canals and utriculus**: Incorrect, as semicircular canals do not contain maculae; they have cristae for dynamic balance.
- **Utriculus and lagen**: Incorrect, as "lagen" is not a recognized term in this context.
- **Utriculus**: Incorrect, as macula is present in both utriculus and saccule.
- **Utriculus and sacculus**: Correct, as both contain maculae.

5. **Conclusion**: The maculae are present in the utriculus and saccule, making option 4 the correct answer.

### Final Answer:
Maculae are present in the **utricle and saccule**.
