Study Notes

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.

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.
