3.
Lens
Correct Answer
E. 5
Explanation
The answer is 5 because it is the only number that is not a part of the sequence. The numbers 1, 2, 3, 4, and 6 are all in a sequential order, but 5 is missing. Therefore, 5 is the correct answer.

Ciliary muscles
Correct Answer
A. 1
Explanation
The ciliary muscles are responsible for controlling the shape of the lens in the eye. This allows the eye to focus on objects at different distances. When the ciliary muscles contract, the lens becomes thicker, allowing for near vision. When the ciliary muscles relax, the lens becomes thinner, allowing for distant vision. Therefore, the ciliary muscles play a crucial role in the eye's ability to focus and adjust its vision.
8.
Rods are responsible for color vision.
Correct Answer
B. False
Explanation
The statement is incorrect. Cones, not rods, are responsible for color vision. Rods are responsible for vision in low light conditions and do not perceive color.
9.
The optic nerves cross at the optic chiasma.
Correct Answer
A. True
Explanation
The optic nerves cross at the optic chiasma, which is a structure located at the base of the brain. This crossing allows for the exchange of information between the left and right visual fields. The optic chiasma plays a crucial role in visual processing and is responsible for the integration of visual information from both eyes. Therefore, the statement "The optic nerves cross at the optic chiasma" is true.

What is the purpose of Papilla?
Correct Answer
A. provide a rough surface to grip food and protect the taste buds
Explanation
The purpose of papilla is to provide a rough surface to grip food and protect the taste buds. The papilla are small bumps on the surface of the tongue that help in manipulating food while eating and enhance the sense of taste. They provide a rough texture that aids in the mechanical breakdown of food and also protect the taste buds from damage.
11.
Which of these are not one of the four kinds of Papilla?
Correct Answer
D. Fungi ate
Explanation
The correct answer is "fungi ate." This is not one of the four kinds of papilla. The other options, filiform, fungiform, and foliate, are all types of papilla found on the tongue.
12.
Which of the following responds to the chemicals dissolved in the saliva and does the actual tasting?
Correct Answer
A. Gustatory cells
Explanation
Gustatory cells are responsible for responding to the chemicals dissolved in the saliva and performing the actual tasting. These cells are found in taste buds, which are located on the tongue and other parts of the oral cavity. When the chemicals from food or drink come into contact with the gustatory cells, they send signals to the brain, allowing us to perceive different tastes such as sweet, sour, salty, and bitter. Supporting cells provide structural support for the gustatory cells, taste pores are openings on the surface of taste buds, and gustatory hairs are tiny projections on the gustatory cells that come into contact with the chemicals in the saliva.
13.
How many tastes does your tongue recognize?
Correct Answer
D. 5
Explanation
The tongue can recognize five tastes: sweet, sour, salty, bitter, and umami. These tastes are detected by taste buds on the tongue, which send signals to the brain to interpret the taste. Each taste serves a different purpose, with sweet indicating energy-rich foods, sour indicating potentially harmful foods, salty indicating the presence of essential minerals, bitter indicating potential toxins, and umami indicating the presence of proteins.
14.
Which of the following hangs out near the taste pore waiting for a food molecule to come in contact with it?
Correct Answer
C. Gustatory hair
Explanation
Gustatory hairs are the structures that hang out near the taste pore waiting for a food molecule to come in contact with them. These hairs are found on the taste buds, which are responsible for detecting and transmitting taste signals to the brain. When a food molecule comes in contact with the gustatory hairs, it triggers a chemical reaction that sends signals to the brain, allowing us to perceive taste.
15.
Olfactory receptor cell
Correct Answer
D. J
Explanation
Olfactory receptor cells are specialized nerve cells located in the nasal cavity that are responsible for detecting and transmitting information about smells to the brain. They have specialized receptors on their surface that bind to odor molecules, triggering a signal that is sent to the brain for interpretation. Olfactory receptor cells play a crucial role in our sense of smell.

The outside of the ear is called the Anvil.
Correct Answer
B. False
Explanation
The outside of the ear is not called the Anvil. The Anvil is one of the three small bones located in the middle ear, also known as the incus. The outside of the ear is called the pinna or auricle.
18.
Cochlea
Correct Answer
E. E
19.
TYMPANIC MEMBRANE
Correct Answer
C. L
Explanation
In the given question, the letters J to M and E to H represent the different parts of the ear. The correct answer, L, represents the Tympanic Membrane, which is also known as the eardrum. The eardrum is a thin, cone-shaped membrane that separates the outer ear from the middle ear. It plays a crucial role in transmitting sound vibrations from the outer ear to the middle ear, where they are further processed and transmitted to the inner ear.
20.
HAMMER (MALLEUS)
Correct Answer
F. F
Explanation
The correct answer is F. The letters in the given sequence are in alphabetical order. Starting from H, each subsequent letter is the next letter in the alphabet. Therefore, F is the correct answer as it comes after E.
21.
Vestibulocochlear nerve
Correct Answer
D. D
Explanation
The correct answer is D. The vestibulocochlear nerve is responsible for transmitting sensory information from the inner ear to the brain. It is involved in both hearing (cochlear portion) and balance (vestibular portion). This nerve plays a crucial role in our ability to perceive sound and maintain equilibrium.

Correct Answer
malleus incus stapes
Malleus Incus Stapes
Explanation
The three different bones in the ear are the malleus, incus, and stapes. These bones are located in the middle ear and are also known as the ossicles. The malleus is attached to the eardrum and transmits sound vibrations to the incus. The incus then passes the vibrations to the stapes, which in turn sends them to the inner ear. These bones play a crucial role in amplifying and transmitting sound waves, allowing us to hear.

Correct Answer
fluid
Explanation
The inner ear is filled with fluid. This fluid, known as endolymph, plays a crucial role in the process of hearing. It helps to transmit sound vibrations from the outer and middle ear to the cochlea, where they are converted into electrical signals that can be interpreted by the brain. The fluid also helps to maintain the balance and equilibrium of the body.
