The atomic number of any atom is equal to the number of electrons in its nucleus and is written as a subscript to the left of its atomic symbol.

Although all skeletal muscles have different shapes, the fascicle arrangement of each muscle is exactly the same.

Projection fibers in the brain mainly connect the right and left hemispheres.

All visceral organs receive dual innervation from both the sympathetic and parasympathetic divisions of the ANS.

Phagocytosis is used by the cells to secrete intracellular substances to the outside of the cell.

A motor neuron and all the muscle cells that it stimulates are referred to as a motor end plate.

Connective tissues that possess a large quantity of collagen fibers often provide the framework for organs such as the spleen and lymph nodes.

Aquaporins are believed to be present in red blood cells and kidney tubules, but not in any other cells in the body.

Lamellar corpuscles can only be exteroceptors or proprioceptors.

Albuterol (Ventolin) binds to $\beta2$ receptors and is used by asthma patients to constrict the bronchioles of the lungs and ease breathing.

Triglycerides are a poor source of stored energy.

Telomeres are the regions of chromosomes that code for the protein ubiquitin.

The frontal bone articulates with the parietal bone by means of the sagittal suture.

The facial (VII), glossopharyngeal (IX), and vagus (X) nerves contain postganglionic fibers of the parasympathetic nervous system.

The gray rami communicantes consist of myelinated postganglionic fibers.

Muscle contraction will always promote movement of body parts regardless of how they are attached.

Thermoregulatory responses to increased heat are mediated by the parasympathetic nervous division.

The sympathetic and parasympathetic divisions of the ANS have the same effect on most body organ systems.

During DNA replication, primase is responsible for adding nucleotides to the new strand.

Steroid hormones typically bind to membrane receptors on the cell surface to initiate their effects.

Histology is the study of the function of body parts and how they work.

The gallbladder produces bile, which is essential for the digestion and absorption of fats.

Epithelial tissue is highly vascularized and contains a large amount of extracellular matrix.

The primary function of red blood cells is to transport oxygen and carbon dioxide, while white blood cells are primarily involved in blood clotting.

The myelin sheath is formed by oligodendrocytes in the peripheral nervous system and Schwann cells in the central nervous system.

The resting membrane potential of a neuron is typically -70 mV, meaning the inside of the cell is negatively charged relative to the outside due to a higher concentration of sodium ions inside the cell.

The process of mitosis results in two daughter cells that are genetically identical to each other but different from the parent cell.

The main function of the Golgi apparatus is protein synthesis and packaging.

Positive feedback loops act to maintain homeostasis by reversing the direction of deviation from a set point.

The epidermis is the outermost layer of the skin, composed of dense irregular connective tissue.

Cardiac muscle is under voluntary control and contains intercalated discs.

The sinoatrial (SA) node is located in the wall of the left atrium and is responsible for setting the basic heart rate.

Plasma cells are responsible for producing antibodies and are derived from T lymphocytes.

The function of the enzyme catalase is to break down oxygen into hydrogen peroxide and water.

Transitional epithelium is primarily found in the lining of the stomach.

The hypothalamus controls body temperature, hunger, and thirst and it accomplishes this through the release of hormones and by altering both sympathetic and parasympathetic activities.

The inferior vena cava carries oxygenated blood from the lungs back to the left atrium of the heart.
