Self-Concept – thoughts and feelings about us are formed by experiences, perceptions, feedback, and culture Self-Esteem – what a person thinks is important, by analyzing how well our behavior conforms to self ideal Authoritarian parents – rigid rules, strict obedience to authority, children expected to obey without question, adult like responsibilities

Authoritative parents – supply firm and consistent guidance, combined with love and affection, give reason for rules Central Nervous System (CNS) – included all of the neurons and nerve fibers in the spinal cord and brain System of nerves, most important, complex Controls behaviors and mental processes Two components are the brain and the spinal cord Peripheral Nervous system (PNS) – includes all neurons outside the spinal cord and brain Divided into TWO PARTS – Somatic nervous system – includes neurons outside the CNS that we have voluntary control, eyes, ears, o Also called Sensory Somatic Nervous System Autonomic nervous system (ANS) – serves muscles (bladder and diaphragm) , independent of CNS o ALSO TWO PARTS Sympathetic division – active when a person is emotionally excited – “fight or flight” Parasympathetic division – active when the body is relaxed Work opposite each other Neurons - very, very small nerve cells. The function of a Neuron is to transmit neural impulses from one place in the nervous system to another o Activity within nerve cell is electrical o Activity between nerve cells is chemical Building blocks of the nervous system We have billions Dendrites, axon, and presynaptic terminals o Dendrites extensions reach out to receive messages from other neurons and send to the cell body Neurons have a cell body- which is the largest concentration of mass of the cell, it contains the nucleus of the cell, which, in turn contains the genetic information that keeps the cell functioning Neurons in their resting state is said to be polarized Sensory neurons – impulses are relayed to the brain and spinal cord to the central nervous system Motor neurons – carry impulses away from the brain and spinal cord towards muscles and glands – away from central nervous system Interneuron’s – transmit impulses from one part of the brain or spinal cord to another Neuron Threshold – minimum amount of stimulation required to get a neuron to fire. Synapse – is the point of connection between two neurons or a neuron and a muscle or gland Neuron impulses must be transmitted from neuron to neuron, this takes place at the synapse Axon Terminals – at the end of an axon are the “senders”

Contains chemical molecules called vesicles Neurotransmitters are the chemicals released from the vesicles o Neurotransmitters special chemicals that enable neurons to pass messages to one another Synaptic Cleft – when Neurotransmitters flood into space between the axon of one neuron and the dendrite of the next neuron , this is caused by an action potential

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
