Nervous System Functions Sensory input sensory receptors monitor
- Slides: 27
Nervous System
Functions • Sensory input - sensory receptors monitor changes occurring inside and outside the body • Integration – processes sensory input and decides what to do • Motor output – the response
Neurons (Nerve Cells) • They have extreme longevity (can function for >100 years) • They are amitotic (do not divide) • High metabolic rate – needs a lot of oxygen and glucose
The impulse travels from the dendrite end to the synapse
Protein gates and pumps in the cell membrane control the movement and concentration of Na and K ions to carry an impulse from one end of the neuron to the other.
Neurotransmitters carry the impulse from one neuron to the next across a gap called the synapse

PNS – Peripheral Nervous System
Sensory Nerves vs. Motor Nerves
What we would look like if our body parts were proportional to the number of sensory nerves connected to these areas.
Somatic Nerves – Control voluntary actions (Muscle movement)
Autonomic Nerves – Control involuntary action (organ control) Parasympathetic Response (Rest & Digest) Sympathetic Response (Fight or Flight)
CNS – Central Nervous System
The Spinal Cord Connects the brain with the nerves of the body
The Human Brain Parietal Lobe (Cerebrum) Thalamus Occipital Lobe (Cerebrum) Cerebellum Ventricle Corpus Collosum Frontal Lobe (Cerebrum) Pons Medulla oblongata Hypothalamus Pituitary Gland Temporal Lobe (Cerebrum) Midbrain
Lobes of the cerebrum
