Gross Anatomy – Forearm Exam With complete solution–
Expert Verified | Latest Questions 2025
What are the types of joints? - Fibrous, cartilage and synovial
Where would you find fibrous joints? - Sutures, syndesmosis, and gomphosis
What are Cartilaginous joints and where are they found? - Connected by cartilage
-Pubic symphysis
-Intervertebral disc
-TMJ
What are synovial joints? - Involve 2 bones with:
-Nerves/blood supply
-Joint capsule
-Synovial membrane (with synovial fluid)
-Articular covering of bone (hyaline cartilage)
-Ligaments (intrinsic and extrinsic)
What are the joints of the forearm? - Humeroulnar, humeroradial, radioulnar joints
What are the movements of the forearm? - Flexion and Extension
Pronation and Supination
What is the carrying angle? - In anatomical position, forearm and hands are normally 5-
15 degrees away from the body
-slightly greater angle on dominant hand
-slightly greater angle in females
What type of joint is the humeroulnar joint? - Hinge joint
What movements occur at the humeroulnar joint? - Flexion and extension
What type of joint is the humeroradial joint? - Hinge and pivot joint
What movements occur at the humeroradial joint? - Aids in flexion/extension but mostly
does rotation (supination/pronation)
What holds the proximal radioulnar joint in place? - Annular lig.
What is dislocation of the proximal radioulnar joint called? - Subluxation
What is the clinical term for a subluxated proximal radioulnar joint? - Nursmaids elbow
, What causes nursemaids elbow? - Sudden jerking of the hand or forearm (parents
pulling their child up by the hand)
What is the distal radioulnar joint held in place by? - Fibrocartilage articular disc
What does the articular distal at the distal radioulnar attach to? - Attaches to distal
radius and styloid process of ulna
What is the interosseous membrane? - CT connecting the radius and ulna
(syndesmosis joint) that separates the anterior and posterior compartments and
-stabilizes
-allows for muscle attachment
-transfers load from wrist to elbow
What muscles are involved in the supination of the forearm? - Biceps brachii (most
powerful) and supinator mm.
What muscles are involved in the pronation of the forearm? - Pronator teres and
pronator quadratus mm.
What bone moves during pronation and supination? - The radius
What is the wrist and what does it consist of? - Transition from forearm to hand.
Includes 8 carpal bones and the radius and ulna (10 total bones)
What movements occur at the wrist? - Abduction/adduction, flexion/extension,
circumduction
What are the carpal bones? - "Some Lovers Try Positions That They Can't Handle"
Proximal: scaphoid, lunate, triquetrum, pisiform
Distal: trapezium, trapezoid, capitate, hamate
What is the anatomical radiocarpal joint? - Joint between distal radius and scaphoid,
lunate and triquetrum
What is the functional radiocarpal joint? - Radius articulating with scaphoid and lunate
What movements occur at the radiocarpal - Flexion/Extension
Abduction/Adduction
Circumduction
What is the intercarpal joint? - Articulation between two rows of carpal bones (increases
range of motion)
What bones make up your fingers? - Phalanges
