It's the bone that is formed behind the nose inside your skull. It has the holes that you breathe through when you breath through your nose.
The frontal bone forms the rostral (anterior) wall of the cranial cavity. It is located at the front of the skull and is responsible for protecting the brain.
Anterior cranial fossa which accommodates the anterior lobe of brain.Middle cranial fossa, much wider than the anterior cranial fossa contain the 2 temporal lobes of brain.Posterior cranial fossa is much shallower and wider than the middle cranial fossa and it accommodates the occipital lobes of the brain.
An animal with these body surfaces typically exhibits bilateral symmetry, meaning its left and right sides are mirror images of each other. This allows for efficient movement and coordination.
The ethmoid bone is a small, delicate bone located in the skull between the eyes. It plays a key role in forming the walls of the eye sockets, nasal cavity, and part of the skull base. The ethmoid bone also houses the ethmoid sinuses, which are air-filled cavities in the face.
The superior and medial nasal conchae are part of the ethmoid bone in the skull. These bony structures help to increase the surface area in the nasal cavity, aiding in air filtration, humidification, and warming as air passes through.
Your question is missing a word. The ethmoid is a bone or sinus in the face. Bilateral means both sides. Mild has the same meaning in medical terms as it has in lay language.
anterior end
they have diagonal symmetry and they have bilateral.
because of the anatomical characteristic of cephalization.
Cephalization
Higher probability of cephilization(or a concentration of nervous tissue at the anterior end of the organism)
Bilateral epistaxis is bleeding from both nostrils. This may be due to an ethmoid hematoma, or due to exercise-induced pulmonary hemorrhage (EIPH). You should talk to your veterinarian about diagnostic and treatment options - there isn't anything you can do about either of these without veterinary advice.
The frontal bone forms the rostral (anterior) wall of the cranial cavity. It is located at the front of the skull and is responsible for protecting the brain.
The cribiform plate and crista galli are part of the Ethmoid Bone. The Cribiform Plate forms the superior surface of the Ethmoid Bone which helps form the roof of the nasal cavities and floor of the anterior cranial fossa. The Crista Galli projects superiorly from the Ethmoid Bone between the Cribiform Plates. The outermost covering of the brain is attached to the Crista Galli and keeps the brain in place.
Bilateral ostiomeatal units refer to the paired anatomical structures in the nasal cavity that allow drainage of the sinuses, specifically the maxillary, frontal, and anterior ethmoid sinuses. When these units are described as "patent," it means that they are open and unobstructed, facilitating normal airflow and drainage. Frontal recesses, which are the spaces leading to the frontal sinuses, being patent indicates that there is no blockage, ensuring proper sinus function and reducing the risk of infections. Overall, patent ostiomeatal units and frontal recesses are crucial for maintaining sinus health.
the ethmoid bone consists of a number of thin-walled cellular cavities, the ethmoidal cells, arranged in three groups, anterior, middle, and posterior forgot to log in last time. but as i said before it is the ethmoid bone
Anterior cranial fossa which accommodates the anterior lobe of brain.Middle cranial fossa, much wider than the anterior cranial fossa contain the 2 temporal lobes of brain.Posterior cranial fossa is much shallower and wider than the middle cranial fossa and it accommodates the occipital lobes of the brain.
