Afferent nerves |
Sensory nerves in the PNS that carry messages from the environment/body to the CNS |
Sensory |
|
Efferent nerves |
Motor nerves in the PNS that carry signals from the CNS to the rest of the body |
Motor nerves |
|
What protects the CNS? |
Bones, meninges and CSF
Blood-brain barriar that protects the train from toxic substances |
**** knows π€·ββοΈ |
|
What are the two types of cells in the nervous system and what do they do? |
Neurons: Transmit information around the nervous system
Glial cells: Provide supporting functions for neurons such as protection from bacteria and damage repair |
|
|
What are the four types of neuron? |
Unipolar (sensory)
Bipolar (interneuron)
Mulitpolar (motor)
Mulitpolar interneuron |
I am totally Bipolar πββοΈππ’ππ³ |
|
What do sensory neurons do? |
Transmit impulses from sense organs and transmit incoming messages from internal organs for pain |
If you did the question on drugs for the essay and you don't know this **** you should drop out. No tea no shade π΅ |
|
What do motor neurons do? |
Carry messages from the brain/spinal cord to muscles and glands |
Muscles |
|
What do interneurons do? |
Carry information between motor and sensory neurons and between other interneurons in the spinal cord/brain |
Between neurons |
|
What are the key parts of a neuron? |
Dendrites - receive signals from other neurons
Cell body - compiles signals received and decides whether to pass them on to the next neuron
Nucleus - within the cell body - contains DNA that specifics the neuron's role.
Axon - carries electrochemical signals that are passed on to the next neuron |
|
|
What is grey matter, white matter and CSF? |
Grey matter - neuron cell bodies
White matter - axons and Glial cells
CSF - Cerebrospinal fluid - the liquid that fills the subarachnoid space providing a cushion surrounding the brain and spinal cord
|
Yeet |
|
What does the hindbrain consist of? |
1. The pons 2. The reticular formation 3. The medulla oblongata 4. The cerebellum |
Sometimes I ask myself why I'm even doing this degree, I ******* hate science. What's the point of it all? Why am I doing this to myself?? |
|
What is the purpose of the medulla oblongata? |
The control of vital functions such as: - heart rate - breathing - blood pressure - reflexes |
Heart rate... Carry on |
|
What do the Pons do? |
Passes information between the cerebellum and cerebral cortex
Regulates sensory analysis
Regulates aspects of sleep |
The bridge |
|
What are the main functions of the reticular formation? |
Attention
Habituation
Regulating the sleep-wake cycle |
This would help me go for a nap, pay (blank) in lectures, and I don't know what the other word means π€π€·ββοΈ |
|
What is the purpose of the cerebellum? |
Coordinates input from the senses and muscles to provides smooth movements, posture and balance |
π€·ββοΈ Brain stuff |
|
What is the purpose of the midbrain and what are the main components? |
A relay centre for visual, auditory and motor system information
Two main components: -Tectum -Substantia nigra |
I dunno π€·ββοΈ |
|
What are the two components of the Tectum? |
The superior colliculi - controls the initial state of visual processing
The inferior colliculi - controls the initial stage of auditory processing |
I am supieror and you are inferior, bitch |
|
What does the Substantia Nigra do? |
Black coloured cells that produce dopamine which facilitates neurons involved with movement and balance |
Black substance, like your poop after Iron tablets π |
|
Define the function of the hippocampus and the result of it's damage |
Responsible for the creation of long term declarative memories
Damage to the hippocampus leads to retrograde amnesia, meaning no new memories can be made.
Maguire et al (2000) - London taxi drivers extensive spatial memory (bigger hippocampus) |
Need to call me an uber and get amnesia |
|
What is the role of the amygdala? |
They play a role in identifying, remembering and responding to fear and aggression. We have one on each side of the brain.
|
THE LITTLE ALMOND GUY |
|
What is the purpose of the hypothalamus? |
Regulates and directs behaviours that are fundamental to survival |
S c i e n c e |
|
What is the purpose of the thalamus? |
A relay station that forwards most sensory information to the cerebral cortex |
Without the hypo π€ |
|
What is the purpose of the occipital lobes? |
Receives visual input from the retina and is responsible for most visual processing of retinal images. Roles include recognising borders, recognising shapes, colour recognition and perceiving objects in motion |
It's VISUAL, you tit |
|
What is the purpose of the temporal lobes? |
Sound processing and localisation (superior area) , memory formation (medial area), face and object recognition (inferior area) |
You should have probably remembered hearing about this area. And recognised its significance |
|
What are the roles of the parietal lobes? |
Processing sensations, spatial awareness and visual attention, symbolic understanding, visual imagery and mental manipulations |
Does a bit of everything really π€·ββοΈ |
