Axial Skeleton
This is the largest hole in a SINGLE bone.
What is the foramen magnum?
This is the BIGGEST hole in the human body, formed by bilaterally pairing the pubis and ischium.
What is the obturator foramen?
True or False: The skeletal system only has 3 functions; Hematopoiesis (making red blood cells), structural support, and storage.
False. What are the other functions?
These are the 3 Functional Classifications of joints.
What are synarthroses, amphiarthroses, and diarthroses?
This is an articulating surface that is large and smooth, and has rounded oval structure.
These bones are part of the cranium.
What are the frontal, occipital, parietal, temporal, sphenoid, and parietal bones?
These are the three bones of the Os Coxae.
What are the ilium, ischium, and pubis?
This cell type degrades bone and can cause osteoperosis.
What is an osteoclast?
These are the 3 structural classifications of joints.
What are synovial, cartilagenous, and fibrous joints?
This structure is a projection and is found only on the femur. There are 2 of them, one greater and one lesser.
What is a trochanter?
These are the 5 types of vertebrae that make up the vertebral column. Must include the total number of vertebrae per type.
What are the cervical (7), thoracic (12), lumbar (5), sacral (5-fused), and coccyx (4-fused)?
These are the two bones of the forearm, listed from MEDIAL TO LATERAL (in anatomical position).
What are the ulna and the radius?
This tissue type is made of protein and ground substances.
What is cartilage?
This synovial joint classification is defined as 2 pieces coming together, and it can move freely in one direction with a large range of motion.
What is a hinge joint?
This is an angular extension of a bone relative to the rest of the structure. The most common of these is found in the jaw.
What is a ramus?
These bones house air cavities lined with mucosa within the skull. These cavities function to lighten the skull and to humidify and warm air.
What are the frontal, ethmoid, sphenoid, and maxillary bones?
These are the carpal bones.
These types of bones are alternatively known as wormian bones.
What are sutures?
This synovial joint type has convex and concave regions that come together allowing for a large range of motion.
What is a saddle joint?
This structure is a flattened or shallow depression in bone. They typically serve as attachment points for muscles, allow for joints to move.
These 7 bones make up the orbit.
What are the frontal, sphenoid, zygomatic, maxillae, palatine, lacrimal, ethmoid, and ethmoid bones?
These are the tarsal bones.
What are the talus, calcaneus (heel), navicular, cuboid, medial cuneiform, intermediate cuneiform, and lateral cuneiform bones?
These are the 3 types of cartilage listed in order of greatest to weakest/
What is fibrocartilage, elastic cartilage, and hyaline cartilage?
This structure is located on the superior surface of the tibia and is the attachment site of the ACL and the PCL.
These are the 5 terms that are often used to name openings or spaces in bones.
What are a canal, fissure, foramen, meatus, and sinus?
