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.
