9-1,2,3 Flashcards
Neural pathway
Links between neurons that “wire” the so that the brain can control different body function , and thinking processes
Cortex
Parts of the brain’s cerebrum. It’s growth permits more complex learning
Myelin
Wax protein based substance that cotes axons making it easier to transmit information from one neuron to the other
Dendrite
a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body.
Synapse
a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
Neurotransmitter
a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.
Cerebrum
Receives information from the senses & directs motor activities.
Pituitar gland
Secretes hormones that regulate growth metabolism abs sexual development
Thalamus
Connects the spinal cord and cerebrum. Controls expression of emotion
Cerebellum
Regulates a coordinate movement posture & balance
Spinal cord
Transits info from the body to the body to the brain and from the brain to the body. It coordinates the activities of the left and right side of the body and controls simple reflexes that dont involve the brain
Perception
The ability to learn from sensory information
Attention span
The length of time a person can concentrate on a task without being bored
Sensorimotor period
First stage of learning from birth to about age 2. During this period babies learn by senses
Imaginative play
Fantasy or dramatic play which imitates real-life situation
Symbolic Thinking
The use of words and numbers to stand for ideas
Object permanence
The concept that object continue to exist when they are out of sight
Concepts
General categories of objects & information
Age appropriate
Sutable for the person age
Child proof
designed to prevent children from injuring themselves or doing damage.
Manipulate
control or influence (a person or situation) cleverly, unfairly, or unscrupulously
Brain stem
Control involuntary activities such as breathing heart rate blood pressure
Neuron
Nerve cell
