Topic 1 Revision Questions Flashcards
Describe in lay terms what flexing your forearm is.
Bending your forearm at the elbow joint up towards shoulder.
Attached to what part of the body would you find a costal cartilage?
Costal cartilage is only found at the anterior ends of the ribs
What is the axial skeleton made up of?
Skull, ribs cage, vertebral column
The pelvis is part of the appendicular skeleton. True or false?
True
Describe the location of the right temporal bone in relation to the right parietal bone.
The right temporal bone is located inferiorly to the right parietal bone.
How many paranasal sinuses are there? Name them.
Frontal sinuses, maxillary sinuses, ethmoid sinuses, sphenoid sinuses
What is the function of the paranasal sinuses?
Reduction of skull weight, contribute to voice resonance, increase the surface area for warming and humidifying inhailed air.
Describe where the ethmoid sinus is found.
Ethmoid bone is located in the midline, posteromedial to the eye sockets.
Where does mucus from the sinuses normally drain?
Drains via ducts into the nasal cavity.
What is distinctive about the hyoid bone, compared to other bones in the body?
The hyoid bone is a ‘free’ bone that does not articulate with any other bones in the skeleton. It is found deep to the mandible (lower jaw), and superior to the larynx. The hyoid bone is held in place by muscles and ligaments.
Name the significant components of the mandible.
Ramus, body, angle, mandibular notch, coronoid process, condyle (rounded bony extension).
What is the name of the joint between the mandible and the rest of the skull? And what type of joint is it?
Temporomandibular joint or TMJ. It is a synovial joint.
What is the type of joint found between bones in the skull? Name it and describe it.
SUTURES – they are very tightly interlocking fibrous joints.
What is the difference between the condyle and the coronoid process, and where would you find them?
The condyle is a rounded bony extension that articulates with the temporal bone, forming the TMJ. Where as the coronoid process is a bony protrusion located anterior to the condyle. They are found on the mandible.
What is a foramen and what is its function, especially in relation to the skull?
A foramen is a hole in the bone and its function is to allow nerves,veins and arteries to pass through. Major foramen in the skull is the foramen magnum, which is the hole whereby the spinal cord exits the skull.
What is a process? Name a process in the skull.
A process is a bony protrusion point where ligaments and muscles attach. Mastoid process, styloid process…
In the peripheral nervous system, what is meant by the term “motor”?
Motor – this is information travelling from the CNS to muscles and some types of glands, and controls movement (and some glandular secretions). Motor nerves do not travel to any other types of tissues. Motor nerve fibres may be voluntary or involuntary.
What are some differences between an artery and a vein?
Arteries carry oxygenated blood away from the heart to the body, and veins carry oxygen-poor blood back from the body to the heart.
What major structure does the maxillary artery supply?
Supplies the temporomandibular joint and associated structures.
The subclavian arteries branch off which major blood vessel on the left?
The left subclavian artery branches off the arch of the aorta.
The left and right vertebral arteries enter the skull through which foramen?
Magnum foramen
The series of large dilated veins where venous blood drains in the brain are called what?
The brain drains blood into the internal jugular brain.
What is the name of the fifth (V) cranial nerve?
Trigeminal nerve
What number is the vestibulocochlear nerve?
VIII
The major part of the bony interior of the nose is formed by the sphenoid bone. True or false?
True
The frontal sinuses are found in which bone of the skull?
Frontal
What is the vomer and where is it located?
The vomer is located in the midsagittal line, in inferior nasal cavity.
Which of the following bones is NOT paired in the skull:
a. Zygomatic
b. Maxillary
c. Lacrimal
d. ethmoid
d. ethmoid
Name 3 bones that articulate with the frontal bone.
parietal, sphenoid, zygomatic bone, maxilla, ethmoid, nasal bone and the lacrimal bone.
Which bone is located in the medial portion of the orbit (eye socket)?
Sphenoid
The cartilage of the external ear is located directly over which bone?
Temporal bone
Another term for the upper jaw is:
maxillae
