• Parts and functions of the brain:

  • Frontal lobe:
  • For judgement, foresight, and voluntary movement.
  • Responsible for smell.
  • Temporal lobe:
  • For intellectual and emotional functions.
  • Responsible for hearing.
  • Parietal lobe:
  • For comprehension of language.
  • Occipital lobe:
  • Primary visual area.
  • Cerebellum:
  • Controls body posture, balance, and coordination.
  • Brainstem:
  • Controls breathing, digestion, heart rate, and blood pressure
• Parts and functions of the nerve cell (neuron):

  • Dendrite:
  • Receives signals from other neurons and transmits them towards the cell body.
  • Nucleus:
  • Controls the cell's activities and contains genetic information essential for its function and reproduction.
  • Cell body:
  • Integrates and processes signals from dendrites.
  • Axon:
  • Carries signals away from the cell body towards other neurons or cells.
  • Axon terminal:
  • Releases neurotransmitters, chemical messengers that carry signals to the next neuron across the synapse
• Parts and functions of the male reproductive system:

  • Testes:
  • Generate sperm cells.
  • Penis:
  • Male external genitalia used for copulation.
  • Scrotum:
  • Keeps the testes at an optimal temperature for sperm production.
  • Epididymis:
  • Stores and matures sperm cells produced in the testes.
  • Urethra:
  • Passage for seminal fluid and urine to leave the body.
  • Vas deferens:
  • Carries mature sperm from the epididymis to the urethra during ejaculation.
  • Prostate gland:
  • Protects and nourishes sperm cells.
  • Seminal vesicle:
  • Secretes fluid rich in sugars and proteins that mix with sperm to form seminal fluid
• Parts and functions of the female reproductive system:

  • Ovary:
  • Produces and releases eggs (ova) through ovulation.
  • Vagina:
  • Female external genitalia used for copulation.
  • Cervix:
  • Allows sperm cells to enter the uterus and protects the uterus from infections.
  • Fallopian tube:
  • Carries eggs from the ovaries to the uterus and provides the site for fertilization.
  • Uterine cavity:
  • Provides a protective and nourishing environment for implantation, growth, and development into a fetus during pregnancy
• Parts and functions of the endocrine system:

  • Hypothalamus:
  • Secretes hormones that regulate bodily functions like hunger, thirst, body temperature, and sleep.
  • Pituitary gland:
  • Secretes hormones that regulate growth, metabolism, reproduction, and other bodily functions.
  • Pineal gland:
  • Produces melatonin hormone, regulating sleep.
  • Thyroid gland:
  • Produces hormones regulating metabolism, energy production, and growth.
  • Adrenal gland:
  • Secretes adrenaline as stress and emergency responders.
  • Pancreas:
  • Produces insulin, hormones regulating blood sugar levels
