AAMI ANATOMY II UNIT 4 2025 WITH 100% ACCURATE
SOLUTIONS
- 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.
- What is the anatomical term for the rounded portion at the proximal end
of the humerus?
Head Trochlea Shaft Neck
- 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 1 / 4
acts as a barrier keeping the upper limb away from the trunk acts as a barrier keeping the upper limb closer to the trunk 2 / 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.
- 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
- 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
- How many carpal bones are found in each wrist?
10 bones 3 / 4
- bones
- bones
12 bones
- 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.
- What bone does the radius articulate with at its proximal end?
Ulna Clavicle Humerus Scapula
- 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
