Lab 5 Terms and Lessons Flashcards
What four regions make up the appendicular skeleton?
-Bones of the upper extremity -Bones of the pelvic girdle -Bones of the lower extremity -Bones of the pectoral girdles
Define fossa
A shallow depression in a bone
Define neck
A narrowed portion, usually located at the base of the “head” of the bone
Define head
A rounded projection that forms part of a joint
Define tubercle
A small, round process
Define sulcus
Groove, crevice or furrow
Define epicondyle
A projection superior to a condyle
Define tuberosity
A rough, elevated surface
Define notch
A V-like depression in the margin or edge of a flat area
Define crest
Moderately raised and therefore prominent ridge
Define spine
A sharp, pointed, slender projection
Define trochanter
Large blunt bump-like projection (larger than a tubercle)
Define malleolus
The bony prominence on each side of the human ankle
What bones are the pectoral girdles (2) made up of?
-Scapula -Clavicle
What is the clavicle known as?
“Collar bone”
What is significant about the claviculosternal articulation?
It is the only point of attachment of the upper limb
What are the two features of the clavicle?
-Acromial end -Sternal end

What is the scapula known as?
“Shoulder blade”
What are the 9 features of the scapula?
- Acromion
- Spine
- Glenoid cavity
- Coracoid process
- Suprascapular fossa
- Infraspinous fossa
- Subscapular fossa
- Lateral border
- Medial border

What does the anterior view of the scapula look like? And what featurs can you see?
- Acromion
- Coracoid process
- Glenoid cavity
- Lateral border
- Subscapular fossa
- Medial border

What do you need in order to side bones?
- Need a later/medial feature
- Need an anterior/posterior feature
How can we side the scapula?
-Glenoid cavity faces laterally and the spine faces posteriorly

How does the clavicle and and the scapula articulate?
The acromial end of the clavicle articulates with the acromial process of the scapula
How is the pectoral girdle attached to the axial skeleton?
By the articulation of the sternal end of the clavicle with the clavicular notch of the manubrium of the sternum
