How are pubic lice diagnosed?
Pubic lice are diagnosed by inspection, noting the presence of insects in the genital area.It is usually easier for the doctor to see marks from the patient's scratching than the bites from the lice, but pubic lice sometimes produce small bluish spots called maculae ceruleae on the patient's trunk or thighs.
What do the maculae in the utricle and saccule sense?
The maculae in the utricle and saccule sense linear acceleration and head position relative to gravity. They are specialized structures in the inner ear that contain hair cells sensitive to movement and play a key role in our sense of balance and spatial orientation.
Sites of the maculae?
otoliths and vestibular nerve
What are the small crystals that activate maculae?
crista
What are the two small chambers containing maculae?
Vestibule
What site of the maculae?
Utricle in vestible and saccule in vestibule.
What are sites of the maculae?
The maculae, or macula is an area in the retina of the eye that is responsible for central vision. There are two main types of maculae: the fovea centralis, which is located at the center of the macula, and the parafovea, which surrounds the fovea. These structures are crucial for detailed vision and color perception.
The hair cells of the utricle and saccule are clustered in?
The hair cells of the utricle and saccule are clustered in structures called maculae. These maculae are specialized sensory regions within the inner ear that detect changes in head position and linear acceleration. The hair cells within the maculae are essential for signaling information related to balance and spatial orientation to the brain.
Which two sensory systems contain structures called maculae?
The vestibular system and the auditory system each contain structures called maculae. In the vestibular system, the maculae are found in the utricle and saccule of the inner ear and help detect linear acceleration. In the auditory system, the macula is a part of the cochlea and is involved in detecting sound vibrations.
Inner ear consists of what two complex structures?
The inner ear consists of the cochlea, which is responsible for hearing, and the vestibular system, which is responsible for balance and spatial orientation.
What is macula of the ear?
Also called maculae provide information on head position (static equilibrium), as well as linear acceleration and deceleration, a type of dynamic equilibrium. The maculae consist of hair cells with hair bundles and supporting cells.
Which of the following correctly matches the equilibrium receptor to the type of equilibrium it monitors?
maculae/static equilibrium
