CNS
acts as body's control center, processes and interprets information, controls thoughts, emotions, movements and reflexes
located within skull and spine
What division of nervous system am I?
Central Nervous System
interacts with external environment
connects cns to the rest of the body
outside the skull and spine
What division of nervous system is this?
Peripheral nervous system
autonomic nerves that project from CNS in the lumbar (small of back) and thoracic (chest area) regions of spinal cord
I make changes to psychological arousal
I make the nerves stimulate organize and mobilize energy resources in threatening situations
what am I?
sympathetic nervous system
The largest glia, performs multiple functions
what glial cell am I?
astroglia in the CNS
what is a bundle of axons in CNS called?
tracts
part of PNS that interacts with external environment
afferent nerves and efferent nerves
what am I?
somatic nervous system (SNS)
autonomic motor nerves that project from the brain to the sacral (lower back) region of spinal cord
I make changes indicative of psychological relaxation
What am I?
parasympathetic nervous system
Myelination of pns axons occur. I guide regrowth of damaged axons after injury, provide a supportive environment for regeneration process. I help maintain the health, providing nutrients and removing waste products. What glial cell am I?
Schwann cells, in the PNS
cluster of neurons cell bodies in CNS called?
nuclei
regulates body's internal environment
afferent and efferent nerves
what am I?
Autonomic nervous system (ANS)
afferent nerves and efferent nerves in the somatic nervous system
afferent nerves: carry sensory signals from the skin, skeletal muscles, joints, eyes, ears to --> CNS
efferent nerves: carry motor signals from CNS--> skeletal muscles
what is coronal
frontal
I provide Myelination in the CNS.I provide metabolic support to neurons, helping to maintain their health and function. I help regulate ion balance around neurons, important for neuron signaling. what glial cell am I?
oligodendrocytes
what is afferent and efferent nerves in ANS?
afferent: carries sensory signals from internal organs to --> the CNS (advance, approach, arrive)
efferent: carries motor signals from CNS to --> internal organs
(exit, embark, escape)
what is a bundle of axons in PNS
nerve
slicing center of the brain into 2 hemispheres. What plane am I?
sagittal plane
I am the immune system responsibilities, role in cell death, synapse information, and synapse elimination. small glial cell. what glial cell am I?
microglia in CNS
What is apart of efferent nerves?
sympathetic nervous system and parasympathetic nervous system
what is a cluster of neuron cell bodies in PNS called?
Ganglia
Does not have an axon, gives rise to several dendrites. What am I?
2 processes, a single axon and a single dendrite. What am I?
multiple dendrites and an axon extending from soma. What am I?
1 process that then splits into 2, connecting both axon and dendrites. What am I?
multipolar interneuron
Bipolar neuron
Multipolar neuron
unipolar neuron
slicing brain in a right angle to any long narrow spinal cord or nerve. what am I?
cross section
