AAMI ANATOMY II UNIT 4 2025 WITH 100% ACCURATE
SOLUTIONS
1. Describe the position of the Pisiform bone in relation to the carpal bones
of the wrist.
The Pisiform bone is located on the dorsal side of the wrist and is
distal to the carpal bones.
The Pisiform bone is located at the base of the thumb and is distal
to the radius.
The Pisiform bone is a small carpal bone that is located on the
palmar side and is considered to be proximal to the distal row of
carpal bones.
The Pisiform bone is located in the middle of the wrist and is equal
in distance to all carpal bones.
2. What is the anatomical term for the rounded portion at the proximal end
of the humerus?
Head
Trochlea
Shaft
Neck
3. Clavicle (collar bone)
acts as a strut keeping the upper limb away from the trunk
acts as a strut keeping the upper limb closer to the trunk
,acts as a barrier keeping the upper limb away from the trunk
acts as a barrier keeping the upper limb closer to the trunk
,4. Describe the role of the acromion process in the acromioclavicular
articulation.
The acromion process articulates with the acromial end of the
clavicle to form the acromioclavicular articulation, which allows
for shoulder movement.
The acromion process serves as an attachment point for muscles
that stabilize the shoulder joint.
The acromion process connects the scapula to the humerus,
facilitating arm rotation.
The acromion process protects the underlying muscles from injury
during arm movements.
5. If a fracture occurs at the aromial end of the clavicle, which joint would
be directly affected?
Elbow joint
Sternoclavicular joint
Glenohumeral joint
Acromioclavicular joint
6. If a patient has an injury to the sternal end of the clavicle, what functional
impairment might they experience?
Reduced grip strength
Loss of wrist function
Inability to flex the elbow
Limited shoulder mobility
7. How many carpal bones are found in each wrist?
10 bones
, 6 bones
8 bones
12 bones
8. Describe the location of the Trapezium bone in relation to the carpal
bones of the wrist.
The Trapezium bone is posterior to the Pisiform bone and distal to
the Scaphoid bone.
The Trapezium bone is located at the base of the thumb and is
lateral to the Scaphoid bone.
The Trapezium bone is superior to the Capitate bone and anterior
to the Hamate bone.
The Trapezium bone is medial to the Capitate bone and proximal
to the Hamate bone.
9. What bone does the radius articulate with at its proximal end?
Ulna
Clavicle
Humerus
Scapula
10. What is the greater tubercle of the humerus?
large rounded portion that articulates with the glenoid fossa of
the scapula
lateral projection just distal to the head; serves as an insertion
for lots of muscles
oblique groove that lies just distal to the head of the humerus
anterior projection; serves as an insertion for lots of muscles
