Anatomy and physiology of smell: a system that detects odors
in the nasal mucosa, it transmits signals through the olfactory
nerve and processes them in the olfactory bulb in the brain.
Anatomy of the lacrimal glands: eye structures that produce
tears, lubricate the surface, remove particles, and protect
against infections, maintaining a balance between production
and drainage.
Forced phonation: excessive voice use increases pressure
on the vocal cords, leading to fatigue, irritation, or injury,
affecting voice quality without proper vocal techniques.
Lacrimal glands: structures in the upper outer eye that produce
tears, lubricate the ocular surface, remove particles, and protect
against infections with substances like antibodies.
Larynx anatomy: an organ of the respiratory system with vocal
cords, cartilages, and epiglottis that regulate airflow, produce voice,
and protect the airways.
Larynx anatomy: a cartilaginous organ in the neck that
regulates airflow, houses the vocal cords for phonation,
and protects airways through the epiglottis.
Normal phonation: a process where the vocal cords vibrate as air
passes from the lungs, producing sound and allowing modulation
of pitch, volume, and intonation in speech.
Olfactory bulb anatomy: a structure at the base of the brain
that receives signals from the olfactory mucosa via the olfactory
nerve and processes odor information.
Olfactory nerve diagram: the first cranial nerve that carries
signals from the olfactory mucosa to the olfactory bulb, enabling
odor perception and identification.
Palatine tonsils: lymphoid organs in the oropharynx that
are part of the immune system, filtering bacteria and viruses
and helping protect the body from infections.
Paranasal sinuses in the coronal plane: shows the frontal sinus
in the forehead, its connection to the nasal cavity, and its roles
in voice resonance, skull protection, and air conditioning.
