    11. Supra-orbital foramen is on:

    • Frontal Bone

    • Zygoma

    • Maxilla

    • Temporal Bone

    Correct Answer
    A. Frontal Bone
    Explanation
    The supra-orbital foramen is a small opening located on the frontal bone, which is the bone that forms the forehead and the upper part of the eye sockets. This foramen allows for the passage of the supra-orbital nerve and artery, which provide sensory innervation to the forehead, scalp, and the upper eyelid. The zygoma, maxilla, and temporal bone do not have the supra-orbital foramen.

    • Zygoma

    • Lacrimal

    • Palatine

    • Mandible

    Correct Answer
    A. Lacrimal
    Explanation
    The lacrimal bone is the smallest bone of the skull. It is located in the medial wall of the orbit and forms a part of the eye socket. Its main function is to house the lacrimal sac, which collects tears and drains them into the nasal cavity. The lacrimal bone is thin and delicate, making it the smallest bone in the skull.

    16. The suture between parietal and occipital bones is:

    • Coronal suture

    • Lambdoidal suture

    • Squamosal suture

    Correct Answer
    A. Lambdoidal suture
    Explanation
    The suture between the parietal and occipital bones is called the lambdoidal suture. This suture is located at the back of the skull and is named after its resemblance to the Greek letter lambda (Λ). It is a dense, fibrous joint that helps to connect and stabilize the parietal and occipital bones, forming the posterior part of the skull. The lambdoidal suture is important for the overall structure and strength of the skull, as well as for protecting the brain.

    • Dura Mater

    • Subarachnoid space

    • Extradural Space

    • Pia Mater

    Correct Answer
    A. Subarachnoid space
    Explanation
    The cerebrospinal fluid (CSF) is found in the subarachnoid space. This space is located between the arachnoid mater and the pia mater, which are two of the three layers of the meninges that protect the brain and spinal cord. The CSF acts as a cushioning and protective fluid, providing support and nourishment to the central nervous system. It also helps to remove waste products and regulate the chemical environment of the brain and spinal cord.

    29. Frontalis and occipitalis muscles are connected by:

    • Skin

    • Connective tissue

    • Aponeurosis

    • Loose Connective Tissue

    • Pericranium

    Correct Answer
    A. Aponeurosis
    Explanation
    The frontalis and occipitalis muscles are connected by aponeurosis. Aponeurosis is a sheet-like tendon that connects muscles to bones or other muscles. In this case, it connects the frontalis muscle, which is located in the forehead, to the occipitalis muscle, which is located in the back of the head. This connection allows for coordinated movement and function between the two muscles.

    The anterior two-thirds of the tongue receives general sensation from the lingual nerve, which is a branch of the mandibular division of the trigeminal nerve. The lingual nerve supplies sensory innervation to the anterior two-thirds of the tongue, as well as the floor of the mouth and the lingual gingiva. This nerve is responsible for transmitting sensations such as touch, temperature, and pain from these areas to the brain.

    • Glossopharyngeal nerve

    • Tongue tie

    • Lingual nerve

    • Tensor veli palatini muscle

    Correct Answer
    A. Glossopharyngeal nerve
    Explanation
    The glossopharyngeal nerve is responsible for providing general sensation and taste to the posterior third of the tongue. This nerve carries sensory information from the tongue and relays it to the brain, allowing us to perceive touch, temperature, and taste sensations in this area. The other options, such as tongue tie, lingual nerve, and tensor veli palatini muscle, are not involved in the sensation and taste of the posterior third of the tongue.

    • Fungiform

    • Tongue tie

    • Lingual nerve

    • Tensor veli palatini muscle

    Correct Answer
    A. Tongue tie
    Explanation
    The restriction of tongue movement, which is caused by the lingual frenulum, is referred to as "tongue tie." The lingual frenulum is a small band of tissue that connects the tongue to the floor of the mouth. When this band is too tight or short, it can restrict the movement of the tongue, leading to a condition known as tongue tie. This can affect speech, eating, and other oral functions.

    • Facial artery, retromandibular nerve, and external carotid artery

    • Facial artery, retromandibular vein, and internal carotid artery

    • Facial artery, retromandubular artery, external carotid artery

    Correct Answer
    A. Facial nerve, retromandibular vein, and external carotid artery
    Explanation
    The correct answer is Facial nerve, retromandibular vein, and external carotid artery. The parotid gland is a major salivary gland located in front of the ear, and these structures are all found within it. The facial nerve is responsible for controlling the muscles of facial expression, the retromandibular vein drains blood from the face and scalp, and the external carotid artery supplies blood to the face and neck.

    135. 3 branches of lingual artery are

    • Deep lingual artery

    • Dorsal lingual artery

    • Sublingual artery

    • Deep lingual artery, dorsal lingual artery, and sublingual artery

    Correct Answer
    A. Deep lingual artery, dorsal lingual artery, and sublingual artery
    Explanation
    The three branches of the lingual artery are the deep lingual artery, dorsal lingual artery, and sublingual artery. These branches supply blood to different areas of the tongue and surrounding structures. The deep lingual artery runs deep within the tongue, providing blood to the posterior part of the tongue. The dorsal lingual artery supplies blood to the upper surface of the tongue. The sublingual artery supplies blood to the floor of the mouth and the sublingual gland. Together, these branches ensure proper blood supply to the tongue and its associated structures.
