Anatomy 3 50%

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.
