Which of the following best describes the function of the sympathetic nervous system?
Which of the following best describes the function of the sympathetic nervous system?
- It prepares the body for 'fight or flight' responses. (correct)
- It controls involuntary actions like digestion and heart rate.
- It regulates the release of hormones from endocrine glands.
- It is responsible for voluntary movement and sensory input.
What is the role of the sodium-potassium pump in nerve impulse transmission?
What is the role of the sodium-potassium pump in nerve impulse transmission?
- It releases neurotransmitters into the synaptic cleft.
- It generates an action potential by moving ions across the neuron's membrane. (correct)
- It acts as an insulator, preventing the nerve impulse from dissipating.
- It helps to reabsorb neurotransmitters after they have been released.

- Luteinizing hormone (LH) (correct)
- Thyroxine
- Follicle-stimulating hormone (FSH)
- Insulin

Mitosis
Mitosis
The process of cell division that produces two genetically identical daughter cells. It's essential for growth, repair, and development.
Meiosis
Meiosis
A type of cell division that produces four unique gametes (sex cells) with half the number of chromosomes. It's crucial for sexual reproduction.
Fertilization
Fertilization
The process of fusing a sperm and egg cell to form a zygote, marking the beginning of a new organism.

Nervous System Review
- Divisions of the Nervous System: Neurons, types, impulses (sodium-potassium pump), synapses (neurotransmitters), excitatory and inhibitory neurotransmitters.
- Reflex Arc: Five parts, mechanisms, and function.
- Central Nervous System (CNS): Brain (and four lobes), functions.
- Peripheral Nervous System (PNS): Function, somatic and autonomic nervous systems (sympathetic and parasympathetic).
- Eye: Parts, functions, and pathway of light; rods and cones; visual disorders.
Endocrine System Review
- Hormones: Steroid and protein hormones, examples.
