Example Question #451 : Gross Anatomy
The head of the radius articulates with which bony prominence?
Capitellum of the humerus
Olecranon fossa of humerus
Scaphoid bone
Ulnar styloid process
Trochlea of humerus
Capitellum of the humerus
The radiohumeral joint of the elbow is formed by the articulation between the head of the radius, and the capitellum of the humerus. While the trochlea of the humerus, and the olecranon fossa do form part of the elbow, they articulate with the ulna. The scaphoid does articulate with the raidius, but at the distal end of the bone.
Example Question #8 : Identifying Joints Of The Extremities
What kind of joint is the elbow?
Hinge
Saddle
Ball and socket
Gliding
Hinge
The elbow is a hinge joint, as it is only about to move in one plane of motion. The thumb is a saddle joint as it can move in multiple directions. The bones of the wrist are gliding joints as they are two flat surfaces moving over each other. Lastly, the shoulder is an example of ball and socket as it has a very wide range of motion.
Example Question #452 : Gross Anatomy
Which of the following two shoulder joints work together to combine movements to allow for an increase in "reach" of the upper limb?
Sternohumeral and glenohumeral
Acromioclavicular and sternohumeral
Sternoclavicular and acromioclavicular
Glenohumeral and acromioclavicular
Sternoclavicular and glenohumeral
Sternoclavicular and acromioclavicular
The sternoclavicular and acromioclavicular joints link two bones of the pectoral girdle to each other and to the trunk of the body. They also combine their movements to increase reach length of the upper limb. They are both synovial joints and surrounded by a joint capsule with numerous ligaments to reinforce their movements. The glenohumeral joint serves in articulation of the humerus and scapula. The Sternohumeral joint does not exist.
Example Question #453 : Gross Anatomy
Which of the following articulates with the radial head of the radius?
Coronoid process
Ulnar notch
Radial tuberosity
Radial notch
Trochlear notch
Radial notch
Radial head articulates with the radial notch. The head of the ulna articulates with the ulnar notch. The trochlear notch articulates with trochlea of the humerus. The radial tuberosity is the attachment site for the long head of the biceps.
Example Question #454 : Gross Anatomy
The zona orbicularis is found in which joint?
Sternoclavicular joint
Glenohumeral joint
Tibiofemoral joint
Acetabulofemoral joint
Acetabulofemoral joint
The zona orbicularis is a portion of the joint capsule of the acetabulofemoral (hip) joint. It is thought to resist distraction (pulling out) of the femur. Additionally, it is believed to help circulate synovial fluid in the joint. As you may recall, synovial fluid helps lubricate joints and provides nutrition to their articular cartilage.
Example Question #455 : Gross Anatomy
What type of joint is the shoulder joint?
Saddle
Ball
Ball and socket
Hinge
Fused
Ball and socket
The shoulder, similar to the hip is formed by a ball-and-socket joint. The ball is created by the head of the humerus, while the socket is created by the glenoid cavity. This creates a smaller, less stable version of the ball-and-socket joint in the hip
Example Question #456 : Gross Anatomy
The deep lateral rotators of the hip are sometimes called the rotator cuff of the hip. Despite this name, not all of the deep lateral rotators attach to the hip joint capsule, and not all the muscles that attach to the joint capsule laterally rotate the hip. Which muscles do not attach to the hip joint capsule?
Rectus femoris
Piriformis
Obturator externus
Gluteus minimus
Piriformis
The rectus femoris, specifically the reflected head, attaches to the anterosuperior portion of the hip capsule. The gluteus minimus attaches to the superolateral portion of the capsule. Although its contribution to the capsule is relatively small, the obturator externus attaches to the posteroinferior joint capsule. Despite contributing to dynamic hip stability by eccentrically controlling hip internal rotation, the piriformis does not attach to the hip's joint capsule.
Example Question #1 : Identifying Tendons And Ligaments
What nerve is compressed in carpal tunnel syndrome?
Axillary nerve
Radial nerve
Recurrent branch of the median nerve
Median nerve
Ulnar nerve
Median nerve
The median nerve enters the hand through the carpal tunnel with the tendons of the flexor digitorum superficialis, felxor digitorum profundus, and flexor pollicus longus. Carpal tunnel syndrome occurs when the median nerve becomes compressed within the carpal tunnel. Compression of the nerve results in tingling and numbness in the fingers.
Example Question #457 : Gross Anatomy
__________ attach skeletal muscles to bones, and __________ connect one bone to another.
Ligaments . . . tendons
Ligaments . . . aponeuroses
Aponeuroses . . . tendons
Tendons . . . ligaments
Reticular tissues . . . tendons
Tendons . . . ligaments
Tendons always connect muscles to bones, and ligaments always connect bones to bones. Reticular tissues are connective tissue that are found around the liver, kidneys, and other organs. Aponeuroses are connective tissue that primarily binds muscle to muscle.
Example Question #2 : Identifying Tendons And Ligaments
The lateral thickening of the fascia lata forms what?
Anterior rectus sheath
Popliteal fascia
Iliotibial (IT) band
Posterior rectus sheath
Crurial fascia of the leg
Iliotibial (IT) band
The fascia lata of the thigh thickens laterally to form the iliotibial (IT) band. The crurial fascia of the leg is found below the knee. The anterior and posterior rectus sheaths are found in the abdominal region. The popliteal fascia is found on the posterior side of the knee.
