• Reproductive System


  Responsible for the process of reproduction, or the creation of offspring of the same species
• Parts of the human male reproductive system

  • Penis
  • Testes
  • Epididymis
  • Scrotum
  • Urethra
  • Vas deferens
  • Ejaculatory duct
  • Seminal vesicle
  • Prostate gland
  • Bulbourethral gland or Cowper's gland
• Penis


  A hollow tube that also contains the urethra
• Testes


  Responsible for the production of semen, which contains the sperm; the main reproductive organ of males
• Epididymis


  A comma-shaped part of the male reproductive system; stores the sperm and serves as the site for sperm cell maturation
• Scrotum


  A bag- or pouchlike part that holds the testes
• Urethra


  The passageway of both urine and semen
• Vas deferens


  Also known as ductus deferens; a long transport tube that carries the sperm from the epididymis to the ejaculatory duct
• Ejaculatory duct


  Formed by the vas deferens and the seminal vesicle; carries the sperm to the urethra
• Seminal vesicle


  Secretes an alkaline fluid that contains sugar, which provides energy to the sperm cell
• Prostate gland


  Releases a milky fluid that liquefies the semen, making the sperm move faster. The fluid secreted by the prostate gland makes up 25% of the semen
• Bulbourethral gland or Cowper's gland


  Secretes an alkaline substance in the urethra, which neutralizes the acid from the urine. This helps protect the sperm as it passes along the urethra
• Spermatogenesis


  The process of producing the sperm
• Sperm cell


  • Head - encloses the nucleus, which carries the male's genetic material
  • Middle piece - contains the mitochondria that provide energy for the sperm to move
  • Tail - used by the sperm cell for movement
• Testis


  The main organ of the male reproductive system; responsible for the production of sperm
• Testosterone


  Hormone released by the testis that controls the production of sperm and the development of male characteristics
• Female reproductive system


  Secretes hormones that help the female to develop. It also produces the egg cell, which is needed in fertilization
• Parts of the human female reproductive system

  • Ovary
  • Fallopian tube
  • Uterus
  • Cervix
  • Vagina
• Ovary


  Produces the egg cell; the main reproductive organ of the female reproductive system
• Fallopian tube


  Serves as the passageway of the egg; connects the ovaries to the uterus; the site of fertilization
• Uterus


  Also known as the womb; the part where the zygote grows and develops
• Cervix


  The part that separates the uterus from the vagina. The cervix stays closed until the female gives birth
• Vagina


  A hollow tube that serves as the passageway out of the female reproductive system
• Ovulation


  The release of the egg cell from the ovary
• Menstrual cycle


  The cycle experienced by sexually mature women, lasting 28 days
• Menarche


  The first occurrence of menstruation that a woman experiences
• Fertilization


  The process when the egg cell and the sperm cell unite
• Basic functions of the nervous system

  • Sensory
  • Integrative
  • Motor
• Parts of the nervous system

  • Central Nervous System (CNS)
  • Peripheral Nervous System (PNS)
• Central Nervous System (CNS)


  Composed of the brain and the spinal cord; serves as the processing area of the nervous system
• Brain


  The part of the nervous system that processes and interprets the signals transmitted to it
• Spinal cord


  Serves as the connection from the brain to the rest of the body
• Parts of the Peripheral Nervous System

  • Somatic Nervous System
  • Autonomic Nervous System
• Somatic Nervous System


  Includes the motor nerves that connect to the skeletal muscles that function voluntarily
• Autonomic Nervous System


  Regulates the smooth and cardiac muscles as well as the other glands
• Parts of the brain

  • Left hemisphere
  • Right hemisphere
  • Frontal lobe
  • Parietal lobe
  • Occipital lobe
  • Temporal lobe
• Left hemisphere


  Controls the left side of the body; controls different skills such as speaking, writing, numerical, and scientific skills, as well as sign language and reasoning
• Right hemisphere


  Controls the right side of the body; related to spatial intelligence, pattern, and face recognition, as well as musical ability
• Frontal lobe


  Controls some voluntary motor functions, difference moods, and sense of smell
• Parietal lobe


  Controls most of the senses such as touch and taste; also responsible for controlling pain, body temperature, and balance
