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
Part of the nervous system that consists of the brain and spinal cord
Central Nervous System (CNS)
peripheral Nervous System (PNS)
Division of the Nervous system that consists of the network of nerves throughout the body
Central Nervous System (CNS)
Peripheral Nervous System(PNS)
Type of neuron that detects stimuli (heat, touch, pressure, cold, or chemicals)and transmits impulses to the brain and spinal cord
Sensory (afferent)
Interneurons
motor (efferent)
Neurons found only in the CNS, connect the incoming sensory pathways with the outgoing motor pathways.
Sensory (afferent)
Interneurons
Motor (efferent)
Type of neuron that relays messages from the brain to the muscles or gland cells.
Sensory (afferant)
Interneurons
Motor (efferent)
Division of the PNS, That carries signals from the nerve endings to the CNS. Can be in the form of Somatic(voluntary, muscles bones and joints) or Visceral(involuntary, organs, heart, lungs and bladder)
Sensory (afferent Division)
Motor (efferent division)
Division of the PNS that transmits information from the CNS to the rest of the body. Can be in two forms, Somatic(voluntary) and Autonomic(involuntary, sympathetic, fight or flight, raises heart rate) or parasympathetic(calming, reset and digest)
Sensory (afferent)
Motor (efferent)
Part of the structure of a neuron that receives signals from other neurons and conducts the information to the cell body. Some neurons only have one and others have thousands.
soma
dendrites
axon
nodes of ranvier
Part of the structure of a neuron that encases the axons. Schwann cells form this in the PNS and the oligodendrocytes assume the role in the CNS
nodes of ranvier
synaptic knob
myelin sheath
soma
Terminal ending of axon branches. Contains vesicles that contain neurotransmitters.
nodes of ranvier
myelin sheath
synaptic knob
sciatic nerve
What is the blood brain barrier?
It's a membrane surrounding the brain that keeps blood from penetrating brain tissue
It's a membrane surrounding the brain that keeps the blood in the brain separate from the blood in the rest of the body
It's a semi-permeable membrane that permits small molecules like oxygen and carbon dioxide to diffuse across to the brain but blocks larger molecules
It's a semi-permeable membrane that prevents cerebrospinal fluid from leaving the brain and entering the blood stream
