Psyc chapter 3 neurological and genetic basis of behavior Flashcards
There are what three types of neurons
Sensory neurons,
motor neurons,
interneurons
What are neurons
Neurons are specialized cells in the nervous system that send and receive information. Building block.
What are the basic components of a neuron
Soma-cell body,
Dendrites-branches receive data,
Axon-sends information electrochemical.
Structure of a neuron consists of five in what order
Dendrites, Soma, metal sheath, Axon & terminal buttons.
How do neurons communicate
Electrochemical process
How to stop the process of neuron communication
Enzymes are used to break down neurotransmitters and inhibit reuptake
The brain has a blood barrier what does this blood brain barrier help protect
Helps protect against harmful foreign substances that the brain cannot handle
The nervous system and body’s primary information system is divided into two major portions
brain and spinal cord system,
peripheral nervous system which is outside of the brain and spinal cord
The brain has three major regions in a developing embryo what are the
The hindbrain,
the midbrain,
the forebrain
This cerebral cortex is what’s differentiates us from other animals and are humanoid ancestors what is so important about it
The cerebral cortex is the uppermost portion of the forebrain and is considered the thinking center of the brain
There are 4 specialized regions or lobes in the brain what are they
Optical lobe which is in the back of your brain, parietal lobe which is in the front of the optical lobe, temporal lobe, frontal lobe.
The right side of the cerebral cortex is for
Visual, sound, emotion
The left side of the cerebral cortex is for
Language, logic explanations
The main function of the PNS is peripheral nervous system
The main function of the PNS is to connect the central nervous system (CNS) to the limbs and organs, essentially serving as a communication relay going back and forth between the brain and the extremities.
Peripheral nervous system or autonomic nervous system can be further divided into two systems
Sympathetic nervous system deals with threatening situations and parasympathetic nervous system which maintains body energy
The spinal cord connects the Peripheral nervous system to the
Brain and cerebrospinal fluid protects it.
What is the endocrine system
The endocrine system is a network of clans in various parts of the body to manufacture and secrete hormones directly into the bloodstream
All humans possess 99.9% of the same jeans but genetic variations can affect
Behavior
How many pairs of sex chromosomes do humans have
23 pairs
Can humans have more than two chrome’s and each pair
Yes can have more than two and it is not needed to survive xxy
What is the difference between sex and gender
Sex is a biological status and gender is something that culture stimulates
