The medical term bradykinesia means:
- A.
Abnormal slow growth of long bones
- B.
Joint stiffness
- C.
Inability to coordinate muscles
- D.
Abnormally slow movement
Correct Answer
D. Abnormally slow movementExplanation
Bradykinesia is a medical term that refers to abnormally slow movement. It is a symptom commonly associated with Parkinson's disease, where individuals experience a significant reduction in the speed and fluidity of their movements. This can manifest as a slowness in initiating and executing voluntary movements, resulting in a general lack of coordination and agility. Bradykinesia can affect various motor functions, such as walking, writing, and even facial expressions. It is often accompanied by other symptoms like muscle stiffness and tremors.Rate this question:

Inflammation and degeneration of a joint is known as:
- A.
Spondylarthritis
- B.
Achondroplasia
- C.
Anklyosis
- D.
Arthritis
Correct Answer
D. ArthritisExplanation
Arthritis refers to the inflammation and degeneration of a joint. It is a common condition that causes pain, stiffness, and swelling in the affected joint. Spondylarthritis is a specific type of arthritis that primarily affects the spine. Achondroplasia is a genetic disorder that results in dwarfism and does not involve joint inflammation. Ankylosis refers to the abnormal fusion of bones in a joint, which can be a result of arthritis. Therefore, arthritis is the correct answer as it accurately describes the inflammation and degeneration of a joint.Rate this question:

A medical field that emphasizes the relationship between the musculoskeletal system and overall health with an emphasis on preventative medicine is:
- A.
Orthotics
- B.
Podiatry
- C.
Chiropractic
- D.
Osteopathy
Correct Answer

Adduction
Correct Answer
A. AbductionExplanation
Abduction is the correct answer because it refers to the movement of a body part away from the middle or midline of the body. This movement can occur in various joints, such as the shoulder or hip, and it is the opposite of adduction, which involves moving a body part towards the midline. Inversion and eversion refer to movements of the foot, while abduction is a more general term that can apply to different body parts.Rate this question:

The process of bending a limb is called
- A.
Extension
- B.
Flexion
- C.
Supination
- D.
Pronation
Correct Answer
B. FlexionExplanation
Flexion is the correct answer because it refers to the process of bending a limb. When a joint is flexed, the angle between the bones decreases, bringing the two body parts closer together. This movement is commonly observed in joints such as the elbow, knee, and hip. Supination and pronation, on the other hand, refer to the rotation of the forearm or foot, while extension refers to straightening or increasing the angle between two body parts.Rate this question:

A bone forming cell is an:
- A.
Osteoclast
- B.
Osteoclasis
- C.

- D.
Osteoma
Correct Answer
C. OsteoblastExplanation
An osteoblast is a bone forming cell. Osteoblasts are responsible for synthesizing and secreting the proteins and other components needed to build new bone tissue. They play a crucial role in bone growth, development, and repair. Osteoblasts work in coordination with osteoclasts, which are responsible for breaking down old or damaged bone tissue. Osteoclasis refers to the process of bone fracture or the surgical procedure of breaking a bone, while osteoma refers to a benign tumor composed of bone tissue.Rate this question:

The membrane that forms the covering of bones except at their articular surfaces is:
- A.
Periosteum
- B.
Diaphysis
- C.
Endosteum
- D.
Epiphysis
Correct Answer
A. PeriosteumExplanation
The periosteum is a membrane that covers the surface of bones, except at their articular surfaces. It is a dense connective tissue that contains blood vessels, nerves, and cells involved in bone growth and repair. The periosteum plays a crucial role in bone formation, providing a site for muscle attachment and supplying nutrients to the bone. It also acts as a protective layer, helping to prevent infections and injuries to the underlying bone. Therefore, the periosteum is the correct answer for the membrane that forms the covering of bones, except at their articular surfaces.Rate this question:

Cerebral angiography
- D.
Echoencephalography
Correct Answer
A. ElectroencephalographyExplanation
Electroencephalography is the correct answer because it is the diagnostic procedure that records the electrical impulses of the brain. This procedure involves placing electrodes on the scalp to measure the brain's electrical activity and is commonly used to diagnose epilepsy, sleep disorders, and other neurological conditions. Positron emission tomography (PET) is a different imaging technique that uses radioactive tracers to measure metabolic activity in the brain. Cerebral angiography is a procedure that involves injecting contrast dye into the blood vessels of the brain to visualize blood flow. Echoencephalography is an outdated term that refers to ultrasound imaging of the brain, which is not the same as recording electrical impulses.Rate this question:

Narcolepsy is the correct answer because it is a medical condition characterized by sudden and uncontrollable episodes of sleep. Individuals with narcolepsy often experience excessive daytime sleepiness and may fall asleep at inappropriate times. The term "narcolepsy" is derived from the Greek words "narke" meaning numbness or stupor, and "lepsis" meaning seizure or attack. This term accurately describes the condition of being seized by sleep, distinguishing it from other options such as epilepsy (a neurological disorder characterized by recurrent seizures), syncope (temporary loss of consciousness due to a lack of blood flow to the brain), and phobolepsy (a non-existent medical term).Rate this question:
