|---|---|---|---|---|---|
| show | Sensory organs receive information about the internal and external environments, and transmits messages to the spinal cord and the brain
🗑
|
||||
| Integration | show 🗑
|
||||
| Response | show 🗑
|
||||
| show | Consists of the brain and spinal cord, enclosed by cranium and vertebral column
🗑
|
||||
| show | All of the nervous system except for the brain and spinal cord, composed of nerves and ganglia.
🗑
|
||||
| Nerve | show 🗑
|
||||
| Ganglion | show 🗑
|
||||
| Excitability | show 🗑
|
||||
| show | A universal property of neurons; neurons respond to stimuli by producing electrical signals that are quickly conducted to other cells at distant locations
🗑
|
||||
| Secretion | show 🗑
|
||||
| show | Sensory neurons that conduct responses to the CNS from the sensory organs
🗑
|
||||
| Interneuron | show 🗑
|
||||
| Efferent Neuron | show 🗑
|
||||
| show | Cell body and control center of the neuron; has a single, centrally located nucleus with large nucleolus
🗑
|
||||
| Cytoplasm | show 🗑
|
||||
| show | Consists of dense mesh of microtubules and neurofibrils; compartmentalizes rough RE into Nissil Bodies
🗑
|
||||
| show | Bundles of actin filaments found tin neuron cytoskeleton
🗑
|
||||
| show | Glycogen granules, lipid droplets, melanin, and lipofuscin
🗑
|
||||
| Lipofuscin | show 🗑
|
||||
| show | Vast number of branches coming from a few thick branches from the soma; primary sites for receiving signals from other neurons
🗑
|
||||
| show | Nerve fiber; originates from the axon hillock on one side of the soma. Unbranched for most of its length, and is specialized for rapid conduction of nerve signals to points remote to soma
🗑
|
||||
| Axon collaterals | show 🗑
|
||||
| Axoplasm | show 🗑
|
||||
| show | The plasma membrane of an axon
🗑
|
||||
| show | Fatty sheaths that enclose the axon, insulating it and speeding up transmissions
🗑
|
||||
| Terminal arborization | show 🗑
|
||||
| Synaptic knob | show 🗑
|
||||
| show | The most common neuron, contains one axon and multiple dendrites, and is found in the brain and spinal cord
🗑
|
||||
| Bipolar neuron | show 🗑
|
||||
| show | Contains a single process leading away from the soma; gathers sensory information from the skin and organs to the spinal cord
🗑
|
||||
| show | Contains many dendrites, but no axon. Helps in visual processes.
🗑
|
||||
| Glial cells | show 🗑
|
||||
| show | Glial cell in the CNS that forms the myelin sheath.
🗑
|
||||
| show | Glial cell in the CNS that secretes and circulates cerebrospinal fluid
🗑
|
||||
| show | Glial cell in the CNS that are tiny macrophages, helping to defend the CNS from potential pathogens
🗑
|
||||
| Astrocyte | show 🗑
|
||||
| Nerve growth factors | show 🗑
|
||||
| Astrocytosis | show 🗑
|
||||
| Schwann cell | show 🗑
|
||||
| Satellite cell | show 🗑
|
||||
| Gliomas | show 🗑
|
||||
| Neurilemma | show 🗑
|
||||
| Nodes of Ranvier | show 🗑
|
||||
| show | Myelin-covered segments from one gap to the next
🗑
|
||||
| Initial segment | show 🗑
|
||||
| Trigger zone | show 🗑
|
||||
| show | Destruction of myelin sheath due to an autoimmune attack; nerve conduction disrupted and sensation hampered
🗑
|
||||
| show | Hereditary disorder of infants of Eastern European Jewish ancestry, where glycolipid GM2 accumulates and disrupts conduction of nerve signals
🗑
|
||||
| Mesaxon | show 🗑
