Psch Brain development and function Flashcards
What is the mind-body problem?
The mind-body involves the question of whether our mind and our body are distinct, seperate entities or one whether they are one and the same thing.
What is phrenology?
Phrenology is a term used to describe the study of the relationship between the skull’s surface features and a person’s personality and behavioural characteristics.
What is the spin cord’s role?
The spinal cord links the brain to other parts of the body below the neck.
What are the two main functions of the spinal cord ?
- Receiving sensory information from the body and sending these messages to the brain for processing
- Receiving motor information from the brain and sending it to the relevant parts of the body.
What does spinal reflex mean ?
A spinal reflex occurs when for example you touch something hot and immediately take your hand off. The nerves in your hand send a message to the central nervous system where it reaches the spinal cord first and immediate response occurs to protect you from further harm.
What is the function of glial cells ?
Glial cells provide support for neuronal function. For example by surrounding neurons to hold them in place.
What are the parts of the neuron from the terminal buttons onwards?
Terminal buttons, myelin, Axon, soma, dendrites
What is the function of the neuron?
A neuron is an individual nerve cell that receives, processes, and/or transmits information to other cells
What are the types of neurons?
- Sensory neurons recieve and carry sensory information
- Motor neurons carry messages from the central nervous system to the cells in the skeletal muscles, organs and glands to stimulate activity.
What are interneurons?
Interneurons act as a link between sensory and motor neurons, relaying information from one to the other.
What is the hindbrain?
The hindbrain is located at the base of the brain around the brain stem. It includes the cerebellum, medulla and pons. These control motor functions and vital, automatic responses such as breathing.
What is the midbrain?
The midbrain is located in the central part of the brain. I is involved in movement, processing of visual, auditory and tactile sensory information, sleep and arousal
What is the forebrain?
The forebrain is located in the front of the brain and stretches over the top of the midbrain. It includes the hypothalamus, the thalamus and the cerebrum. It is responsible for regulating complex cognitive processes such as thinking and emotion and personality.
What does the frontal lobe do?
The frontal lobe is associated with the prefrontal cortex. It is responsible for sophisticated mental abilities such as planning and planning and initiating voluntary bodily movements
Why does the parietal lobe do?
The parietal lobe is associated with the somatosensory cortex. It is involved in receiving and processing bodily sensory information such as touch
