Characteristics of Class Mammalia
Mammals are a class of warm-blooded vertebrates that possess the following characteristics:
• Hair or fur on their bodies
• Mammary glands that produce milk to nourish their young
• Three middle ear bones (incus, malleus, stapes)
• A four-chambered heart
• Diaphragm for respiration
Unusual Characteristic
Thecodont dentition, alveolar lungs, and seven cervical vertebrae are all typical characteristics of the class Mammalia. However, having ten pairs of cranial nerves is not a typical characteristic of mammals. Most mammals have only twelve pairs of cranial nerves, which are responsible for various functions such as sight, hearing, smell, taste, and movement of the face and neck.
Explanation
The cranial nerves are a set of twelve paired nerves that arise from the brain and pass through various openings in the skull to innervate different regions of the head and neck. These nerves are numbered I to XII, and each has a specific function. For example, the olfactory nerve (I) is responsible for the sense of smell, while the optic nerve (II) is responsible for vision.
Conclusion
In summary, having ten pairs of cranial nerves is not a typical characteristic of mammals. Most mammals have only twelve pairs of cranial nerves, which are responsible for various functions such as sight, hearing, smell, taste, and movement of the face and neck.
