What are the three types of bone markings?
There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).
What is a fissure bone marking?
Fissure – An open slit in a bone that usually houses nerves and blood vessels. Examples include superior and inferior orbital fissure. Foramen – A hole through which nerves and blood vessels pass. Examples include supraorbital foramen, infraorbital foramen, and mental foramen on the cranium.
What is the difference between a condyle a process and a foramen?
is that condyle is (anatomy) a smooth prominence on a bone where it forms a joint with another bone while foramen is (anatomy) an opening, an orifice; a short passage.
What bone marking is a hole in a bone?
Learning Objectives
| Bone Markings (Table 7.2) | ||
|---|---|---|
| Marking | Description | Example |
| Fissure | Slit through bone | Auricular fissure |
| Foramen | Hole through bone | Foramen magnum in the occipital bone |
| Meatus | Opening into canal | External auditory meatus |
Is a fissure a depression or opening?
| MARKING | |
|---|---|
| Fissure | Narrow slit or groove between adjacent parts of bone through which blood vessels, nerves or ligaments pass |
| Foramen | Opening (hole) through which blood vessels, nerves or ligaments pass |
| Fossa | Shallow depression |
| Sulcus | Furrow or groove along a bone surface that accommodates a blood vessel, nerve or tendon |
What is the difference between condyle and tubercle?
is that tubercle is (anatomy) a round nodule, small eminence, or warty outgrowth, especially those found on bones for the attachment of a muscle or ligament or small elevations on the surface of a tooth while condyle is (anatomy) a smooth prominence on a bone where it forms a joint with another bone.
What does the tubercle do?
In the human skeleton, a tubercle or tuberosity is a protrusion that serves as an attachment for skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone.
Why do some bones have Foramina fissures passageways and depressions?
Bones have many different types of markings that are associated with muscle attachment points, joints, and passageways for vessels and nerves. A foramen, a type of depression, is a hole in the bone through which nerves and blood vessels pass.
What is a condyle bone marking?
Condyle. Rounded bump or large rounded prominence. Such rounded surfaces usually fit into a fossa on another bone to form a joint.
Which is smaller the foramen ovale or the superior fissure?
The foramen ovale is smaller and round in shape whereas the superior orbital fissure is quite long and narrow in comparison. Also considered to be types of holes in the skull are structures with canal, hiatus, or meatus in their name.
Is there a canal in the condyloid fossa?
Anatomical terms of bone. [edit on Wikidata] The condylar canal (or condyloid canal) is a canal in the condyloid fossa of the lateral parts of occipital bone behind the occipital condyle.
How do you learn the foramina and fissures of the skull?
One way to do this is to learn the foramina and fissures based on the bone in which they are located. Inside the skull however, you can divide the floor or base of the skull into three different shallow depressions known as fossae (anterior, middle, and posterior), and then learn the foramina and fissures associated with each of those.
Why are there fissures in the middle of the skull?
Foramina/Fissures of the Middle Cranial Fossa. It allows the second division of the trigeminal nerve (CNV2), the maxillary nerve, to enter the skull carrying sensory information coming from areas of the face associated with the region under the eyes, and the upper lip, or the skin overlying the maxilla bone.
