Process

A __________________ is a bone marking that serves as a site for tissue attachment or as a part of a joint.

Condyle

A large round protuberance with a smooth articular surface on the end of a bone is a(n) _______________________________

D. outgrowth that may be a point for muscle attachment

A process on a bone is a/an A : depression that allows the passage of soft tissues B : projection through which blood vessels may pass C : attachment site for nerves that serve the bones D : outgrowth that may be a point for muscle attachment

Fissure

A(n) _____________________is a narrow slit in a bone through which blood vessels or nerves pass.

B. Facet, such as those found on the Vertebrae

There is a bone on the lab bench in front of you. On it, you see that there is a smooth and slightly convex articular surface. This bone marking would be a A : facet, such as those found on the femurs B : facet, such as those found on the vertebrae C : head, such as those found on the vertebrae D : head, such as those found on the femurs

Meatus

Tubelike opening.

A. foramen

Which of the following bone markings might accommodate blood vessels? You got it correct : A foramen B tubercle C condyle D trochanter

A. Crest B. Line

Which of the following bone markings refers to ridges on the surface of a bone? Select all that apply. A : crest B : line C : tubercle D : facet E : epicondyle F : trochanter

C. Sulcus

Which of the following describes a furrow along a bone surface to accommodate a blood vessel, nerve, or tendon? A : fossa B : line C : sulcus D : fissure

D. Head

Which of the following is a bone surface marking associated with a joint? A : epicondyle B : trochanter C : fossa D : head

Foramen

Which of the following refers to a hole or cave-like opening in a bone? A : fossa B : meatus C : foramen D : fissure

A. Meatus

Which of the following refers to a tube-like opening in a bone? A : meatus B : fossa C : fissure D : foramen

B : Tubercle D: Line E: Crest 6667890-3

Connective tissue might attach to which of the following types of bone markings? Select all that apply. A : sulcus B : tubercle C : foramen D : line E : Crest

1) Depressions & Openings: Allow for Passage of Soft Tissue 2) Processes: allow for points of attachments

Depressions & Openings in bones allow for _____________ where as Processes allow __________________

can form joints

Depressions/Openings and Processes BOTH ______________

Fossa

Shallow depression.

Head

- (usually) Rounded Articular Projection supported on neck (constricted portion) of bone.

Condyle

- *Large, round protuberance* with a *Smooth Articular* Surface at end of bone.

Epicondyle

- *Roughened* Projection above condyle.

Line (Linea)

- Long, *Narrow* Ridge or Border

Processes

- Projections or outgrowths on bone that form Joints or Attachment Pts. for C.T, such as Tendons & Ligaments

Crest

- Prominent Ridge or *Elongated* projection.

Tubercle

- Rounded Projection that varies in size

Spinous Process

- Sharp, slender projection.

Facet

- Smooth, Flat, slightly concave or convex articular surface.

Tuberosity

- projection that has a Rough, Bumpy Surface and varies in size.

C. a Spinous Process

The bone in front of you has a sharp, slender projection sticking off one side. What would you call this type of marking? A : an epicondyle B : a tuberosity C : a spinous process D : a trochanter
