Fl Neuro Exam Dec 6
| Question | Answer |
|---|---|
| things that make neurons like other cells | 1 nucleus 2 mitochondria 3 ribosomes 4 ER 5 golgi apparatus 6 plasma membrane |
| things that make neurons different from other cells | 1 specialized shape (soma, axon and dendrites) 2. transmit information |
| what the cell membrane is made out of | a phospholipid bi-layer |
| chemicals that move through the phosopholipid bilayer through active or passive transport | H2O, CO2, O2, Na+. Ca2+, K+, Cl- |
| nucleus | part of a neuron that holds DNA |
| mitochondria | part of a neuron that generates energy in the form of ATP |
| ribosomes | part of a neuron that makes proteins from RNA |
| ER | part of a neuron that orders organelles |
| golgi apparatus | part of a neuron that orders proteins |
| dendrites | part of a neuron that receives information |
| axon | part of a neuron that sends information |
| presynaptic terminals | part of a neuron that releases neurotransmitters |
| two types of glia | Oligodendrocyte (CNS) and Schwann (PNS) |
| major divisons of the nervous system | central NS and peripheral NS |
| structures that comprise the CNS | brain and spinal cord |
| divisions of the PNS | autonomic NS (involuntary) and somatic NS (voluntary) |
| divisions of the autonomic NS of the PNS | enteric NS (gastrointestinal), sympathetic NS (fight or flight), parasympathetic NS (vegetative) |
| 3 major divisions of the brain | forebrain, midbrain, hindbrain |
| major structures of the forebrain | cortex, thalamus, hypothalamus |
| major structures of the midbrain | top of the brainstem, colliculi, periaqueductal gray, substantia nigra |
| major structures of the hindbrain | bottom of the brainstem (pons and medulla), cerebellum |
| structures of the brainstem | pons, medulla, midbrain, other central structures |
| function of the medulla | controls vital reflexes |
| function of the the pons | a bridge for crossing axons |
| function of the cerebellum | controls balance, coordination, direction |
| colliculi | part of the midbrain that processes visual and auditory sensory |
| periaqueductal gray | part of the midbrain where opioid receptors block pain (HEROIN!) |
| substantia nigra | thing that deteriorates with Parkinson's |
| thalamus | part of the forebrain that processes sensory info (except olfactory) |
| hypothalamus | conveys messages to the pituitary gland for hormonal release |
| pituitary gland | receives info from the hypothalamus and releases hormones according to it |
| hippocampus | stores memories |
| corpus callosum | joins the two hemispheres of the brain |
