Components of a NeuronComponents of a NeuronSoma (Cell Body): Contains the nucleus (a body within the soma that contains the cell’s hereditary material of the cell) it produces energy that fuels the activity of the cell

Components of a NeuronComponents of a NeuronDendrites: The short, branched projections of a neuron that receive impulses from axons terminal on other neurons and conduct them toward the cell body.

Components of a NeuronComponents of a NeuronAxon: The long projection that transmit impulses away from the cell body to the synapse.

Components of a NeuronComponents of a NeuronMyelin Sheath: A white fatty substance that insulates and protects the axon. The myelin helps speed the impulses.

The loss of muscle control seen with multiple sclerosis is due to a degeneration of myelin sheath.

Components of a NeuronComponents of a NeuronNodes of Ranvier: The widely spaced gaps on the myelin sheath. They further speed transmission of the impulse as it needs to “skip” over the gap

Pituitary Gland: is also known as the “master gland” because it secretes many hormones that affect a wide range of behaviors such as growth, pregnancy, mothering, etc.

Thyroid Gland: Secretes hormones involved in metabolism

Hypothyroidism (too little thyroxin) leads to being overweight

Hyperthyroidism (too much thyroxin) leads to weight loss, inability to sleep, excitability, etc.

Adrenal Gland: The outer layer of the adrenal glands secretes cortical steroids which increase resistance to stress and promote muscle development. Cortical steroids also release stored sugar, making energy available for emergencies.

Testosterone: A male sex hormone produced by the testes in the male.

If, in the prenatal period, testosterone is secreted male sex organs develop. However, if testosterone is NOT secreted, female sex organs develop. In adolescence, testosterone aids in the growth of muscle and bone and in the development of primary and secondary sexual characteristics

Estrogen and Progesterone:

female sex hormones secreted by the ovaries
