The Nervous System

Functions of the Nervous System 1.the center of all thought, learning and memory

Functions of the Nervous System 1.the center of all thought, learning and memory 2.regulates and maintains homeostasis (a state of balance) examples: body temperature, heart rate, respiration,digestion

Functions of the Nervous System 1.the center of all thought, learning and memory 2.regulates and maintains homeostasis (a state of balance) examples: body temperature, heart rate, respiration, digestion 3.keeps us in touch with our internal and external environment

Central Nervous System 1.Made up of brain and spinal cord

Central Nervous System 1.Made up of brain and spinal cord 2.Three main parts of brain: a) Cerebrum- interprets input from senses and controls voluntary muscles

Central Nervous System 1.Made up of brain and spinal cord 2.Three main parts of brain: a) Cerebrum- interprets input from senses and controls voluntary muscles b) Cerebellum- coordinates actions of muscles and helps keep your balance

Central Nervous System 1.Made up of brain and spinal cord 2.Three main parts of brain: a) Cerebrum- interprets input from senses and controls voluntary muscles b) Cerebellum- coordinates actions of muscles and helps keep your balance a) Brainstem- controls homeostasis and coordinatesinvoluntarymuscles

What is this part of the brain called? a)Cerebrum b)Cerebellum c)Brain stem d)Spinal cord

What is the function of the brain stem? a)Controls homeostasis & voluntary muscles b)Controls senses & voluntary muscles c)Controls balance & coordinates muscles d)Controls homeostasis & involuntary muscles

When you feel hungry, what function is your nervous system trying to carry out? a)Maintaining homeostasis b)Moving your body c)Sensing your environment d)Keeping your balance

Nerve Cells Nerve cells are called neurons Impulse- a message carried by a neuron Synapse- the small space that an impulse jumps between neurons

Types of Neurons 1.Sensory neurons: can sense pressure, temperature, pain, and 5 senses in skin, muscles, joints and sense organs (nose, tongue, eyes, ears)

Types of Neurons 2.Motor neurons: stimulate muscle cells throughout the body includes muscles of the heart, diaphragm, intestines, and bladder

Types of Neurons 3.Interneurons: connect other neurons all neurons in the central nervous system (brain, spinal cord) are interneurons

Types of Neurons Reflex- an involuntary response to a stimulus (change in environment) that allows the body to respond quickly without thinking about it

What is an impulse? a)A nerve cell b)A message carried by neurons c)The space between two neurons d)A reflex

What is this structure called? a)Axon b)Synaptic terminal c)Nucleus d)Dendrite

What does a motor neuron stimulate? a)Brain cells b)Sensory organs c)Muscle cells d)Sensory neurons

Which is not true about a reflex? a)It is a quick response. b)It is voluntary. c)It does not require conscious thought. d)It is a response to an external stimulus.
