The Nervous and endocrine Systems

Master the nervous and endocrine systems! Label neurons, identify disorders, and compare hormone types with this biology practice worksheet.

Neuron Labeling: Label this neuron by using the following terms: axon, dendrite, cell body, nucleus, myelin sheath, axon terminal Dendrite Cell body Nucleus myelin sheath axon axon terminal Which of the following is NOT a part of the central nervous system? brain spinal cord peripheral nerves All of these are parts of the central nervous system Nervous System Disorders: Match the nervous system disorder to the correct description. Meningitis Inflammation of the meninges Stroke Blood clot or hemorrage in a blood vessel to the brain Multiple Sclerosis Autoimmune disease that results in loss of the myelin sheath On which type of axon is a nerve impulse the fastest? Myelinated Unmyelinated Fill in the Blanks: Neurotransmitters are chemical messengers that transmit a signal. They are released from the axon terminal, cross the synaptic cleft and bind to receptors on the target cell. List two differences between steroid hormones and protein hormones. All of the following are endocrine organs EXCEPT for the: pancreas thyroid ovaries esophagus Endocrine System Disorders: Match the endocrine system disorders to the correct descriptions. Diabetes Insufficient insulin levels cause a rise in blood glucose Hyperthyroidism Overproduction of thyroid hormones speed up metabolism Pituitary dwarfism Growth hormone deficiency leads to poor growth, short stature
