The nerves connect the body, brain, and spinal cord. A complete nerve cell consists of a cell body with thread-like fibers. The whole thing is called a neuron. Each one can be rather long, and transmits impulses in only one direction. Axons, on one end, conduct impulses away from the cell body. Dendrites, on the other end, conduct impulses to the cell.

The seven top vertebra (in your neck) are the cervicals. The next 12 in your upper back are the thoracics. The next five, below that, are the lumbers in your lower back. Then come five sacral vertebra and, lastly, four coccygeal in your, so-called, "tail bone." Without that section, you could not sit properly.

There are 206 bones in the human body. Six of them are the ossicles in the ear. Infants have about 350 bones; but many of these eventually connect, forming the 206 bones in the adult. The bones provide a solid framework, supporting and shaping the body. They protect delicate or soft parts and anchor the muscles.

Asexual reproduction is done by mitosis, as in protozoa. Human beings reproduce by sexual methods. Each female and male possesses sex glands (gonads) which produce sex cells (gametes). When the male gamete is brought into contact with the female gamete, they unite and form a new single-celled individual (a zygote).

Fertilization - An ovum leaves the ovary about halfway between menstrual cycles; it enters the fallopian tube and travels down toward the uterus. During intercourse, millions of sperm cells (200 million to 400 million) are discharged by ejaculation into the vagina.
