Muscle Movement

• Muscles attached to bones contract, pulling on the bone and causing movement.

Medulla Oblongata

• Contains vital centers for respiration, heart rate, and blood pressure regulation.

Central Nervous System (CNS)

• Incorrect statement: The CNS is responsible for voluntary and involuntary actions. (The CNS is responsible for integrating and coordinating all bodily functions.)

Arrow Indication

• Need the drawing to determine what the arrow indicates.

Nerve Fiber Function

• Afferent nerve fibers conduct information towards the CNS.

Somatic Nervous System

• Correct statement: The Somatic Nervous System controls voluntary skeletal muscle movement.

Tendon Function

• Connects muscle to bone, enabling force transmission for movement.

Hinge Joint

• Allows movement in one plane, like a door hinge.

Sympathetic Trunk Connection

• Splanchnic nerves contain sympathetic postganglionic fibers that connect the sympathetic trunk.

Anterior

• Term refers to the front of the body or structure.

Long Bone Space

• The hollow space in the middle of long bones is filled with bone marrow.

Parasympathetic Neuron Location

• Located in the craniosacral region of the nervous system (brain and sacral spinal cord).

Organ of Corti Location

• Located within the cochlea of the inner ear, responsible for hearing.

Fortifying Nervous System

• Sympathetic nervous system fortifies and accelerates organ activity.

External Muscle Sheath

• Epimysium is the external sheath of muscle that surrounds the entire muscle.

Spinal Nerve Pairs

• 31 pairs of spinal nerves are connected to the spinal cord.

Sigmoid Sinus Blood Flow

• Brings blood from the dural sinuses of the brain.

Axial Skeleton Components

• Clavicle is not part of the axial skeleton.

Blood Plasma Filtration

• Occurs in the glomeruli of the kidneys.

Sagittal Plane

• Divides the body into right and left halves.

Spinal Nerve Plexus

• Lumbo-sacral plexus is not a spinal nerve plexus.

Lymph Fluid vs Blood

• Lymph fluid is a clear fluid that circulates through the lymphatic system, collecting waste and transporting it back to the blood circulation.

Paranasal Sinus Location

• Paranasal sinuses are located within the frontal, ethmoid, sphenoid, and maxillary bones.

Motor Neuron Cell Body Location

• Located in the anterior horn of the spinal cord.

Midbrain Structures

• Substantia nigra is not located in the midbrain.

Tonsils

• Incorrect statement: Tonsils are only located in the throat. (Tonsils are located in the throat and also in the back of the tongue).

Tonsils

• Correct statement: Tonsils are part of the lymphatic system and help fight infections.

Spinal Cord Central Canal

• Contains cerebrospinal fluid.

Lower Respiratory Tract Organs

• Trachea, bronchi, bronchioles, and alveoli are the principal organs of the lower respiratory tract.

Medial

• Refers to the middle or center of the body or structure.

Gastrointestinal Tract Organs

• Liver, pancreas, and gallbladder are not within the gastrointestinal tract.

Vertebrae Bodies Join

• Vertebrae bodies join following structures except anterior longitudinal ligament.

Touch Pathways

• Anterior spinothalamic tract is not a pathway of touch.

Sinoatrial Node

• Structure of the heart responsible for initiating the heartbeat.

Heart Valve Structures

• Endocardium is the inner lining of the heart, including the valves.

Spinal Cord Central Canal Surrounding

• Gray matter surrounds the central canal of the spinal cord.

Pelvic Bones

• Scapula(shoulder blade) is not part of the pelvic bones.

Left Common Carotid Artery Blood Flow

• Brings blood to the left side of the head and neck (including the brain).

Superior

• Term refers to the top or above in the body or structure.

Arrow Indication (Ganglia)

• Need the drawing to determine what the arrow indicates.

Back Extensor

• Erector spinae muscle is the chief extensor of the back.

Thigh Muscle

• Quadriceps femoris muscle is the most powerful muscle of the thigh.

Taenia Coli Location

• Found in the large intestine (colon).

Arrow Indication (Brain Structure)

• Need the drawing to determine what the arrow indicates.

Arrow Indication (Spinal Cord Structure)

• Need the drawing to determine what the arrow indicates.

Proprioceptor Location

• Located in muscles, tendons, joints, and ligaments, provide sensory information about body position and movement.

Vein Without Matching Artery

• Great saphenous vein has no artery by the same name.

Explore how muscles work in conjunction with bones to facilitate body movement. This quiz tests your knowledge on the mechanisms of muscle contractions and their influence on skeletal motion. Understand the role of different muscle types and their attachment to bones.
