Anatomy Chpt 11 Part 1

Type of cell that make up the nervous system that are excitable, impulse-conduction cells that perform the work of the nervous system. handles the role of communication. Three different types include sensory, interneurons, motor

• Neuron

• Neuroglia

Type of cell in the nervous system that protect the neurons. AKA Glial cells, or supportive cells.

• Neurons

• Neuroglia

Type of glial cell that help for the blood brain barrier and provide structural support in the central nervous system. Most numerous of the glial cells

• Astrocytes

• microglia

• ependymal

• oligodendrocytes

Form myelin sheath around nerves in the peripheral nervous system

• oligodendrocytes

• ependymal

• microglia

• Schwann

Performs phagocytosis, engulfing microorganisms and cellular debris

• oligodendrocytes

• ependymal

• microglia

• schwann

Line spinal cord and cavities of the brain. some secrete cerebrospinal fluid, whereas others have cilia that aid fluid circulation

• oligodendrocytes

• ependymal

• microglia

• astrocytes

Form myelin sheath in the brain of the Central Nervous System and spinal cord, speed signal conduction

• Oligodendrocytes

• microglia

• ependymal

• Schwann

Semi Permeable membrane that exists throughout the brain that protects the brain of foreign substances

• glial cells

• blood-brain barrier (BBB)

• cell membrane

• cell wall

Which Body system works to employ chemical messengers called hormones to communicate with cells

• lymphatic system

• Nervous system

• Endocrine system

• Central nervous system

Body system that uses electrical signals to transmit messages at lightning speed

• Respiratory system

• Nervous system

• circulatory system

• lymphatic system
