What are cranial nerves
The document discusses the 12 pairs of cranial nerves, which connect the brain to different parts of the head, neck, and trunk. Each nerve has a corresponding Roman numeral and either sensory or motor functions. The cranial nerves are the olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory, and hypoglossal nerves. They control functions like smell, vision, eye and facial muscle movement, hearing, balance, swallowing, digestion, and tongue movement.
The Nervous System: CNS & PNS
This document provides information about the human nervous system, including:
- The central nervous system (CNS) which includes the brain and spinal cord.
- The peripheral nervous system (PNS) which includes nerves that connect all body parts to the spinal cord, including somatic nerves (voluntary movement and senses) and autonomic nerves (involuntary functions).
- Key parts of the brain like the cerebrum, cerebellum, and brain stem and their functions.
- How the nervous system uses neurons, synapses, and neural pathways to collect sensory input, integrate it in the brain, and result in motor outputs to the body's muscles and glands.
Autonomic Nervous System
The autonomic nervous system regulates involuntary body functions and is divided into the sympathetic and parasympathetic nervous systems. It contains two neurons, with the preganglionic neuron cell body in the CNS and the postganglionic neuron cell body in autonomic ganglia. The sympathetic division is responsible for the fight or flight response and generally opposes the effects of the parasympathetic division, which is responsible for rest and digest functions. The enteric nervous system also helps control the gastrointestinal system independently.
Peripheral Nervous System. Cranial Nerves – Part 1
The document provides information on the structural organization and functional roles of the peripheral nervous system (PNS). It discusses how the PNS is divided into 31 pairs of spinal nerves and 12 pairs of cranial nerves. It also summarizes the key characteristics and functions of each of the 12 cranial nerves.

Minersville HS Applied Anatomy Nervous System
Neurons are specialized cells that communicate via electrical and chemical signals. They consist of a cell body containing the nucleus, along with dendrites that receive signals and a long axon that transmits signals. There are three main types: sensory neurons transmit signals to the central nervous system, motor neurons transmit signals from the CNS to effectors, and interneurons connect sensory and motor neurons within the CNS. The simplest nerve pathway is a reflex arc involving receptors, sensory neurons, interneurons, motor neurons and effectors. The central nervous system coordinates information and consists of the brain and spinal cord. The peripheral nervous system connects the CNS to organs and consists of cranial and spinal nerves.
The Parts & Function of the Brain
The brain can be divided into four lobes - the frontal, parietal, occipital, and temporal lobes. Each lobe is associated with different functions. The frontal lobe is involved in reasoning, motor skills, and language. The parietal lobe processes sensory information like touch. The temporal lobe includes the auditory cortex and hippocampus. The occipital lobe contains the visual cortex and interprets visual stimuli.

Brainstem Physiology
The midbrain connects the brainstem to the forebrain and cerebellum. It consists of the tectum and cerebral peduncles. The tectum contains the superior and inferior colliculi, which are involved in visual and auditory reflexes. The cerebral peduncles contain the substantia nigra and red nucleus. The red nucleus receives input from the motor cortex and dentate nucleus, and sends outputs to control muscle tone, complex movements, righting reflexes, and eye movements.

- The meninges (dura mater, arachnoid mater, pia mater) protect the brain and spinal cord.
- The ventricles and cerebrospinal fluid (CSF) transport CSF within the brain and spinal cord.
- The spinal cord contains gray matter with neurons and white matter with nerve tracts. It relays sensory and motor signals.
- Reflex arcs involve receptors, sensory and motor neurons, and effectors in automatic responses like withdrawal reflexes.
- The brain contains structures like the cerebrum, cerebellum, and brain stem that control functions like memory, movement, and homeostasis.
Nervous system
The nervous system is composed of the central nervous system (CNS; brain and spinal cord) and peripheral nervous system (PNS; nerves of the body). The CNS controls and coordinates all functions through sensory input, integration, and motor output. The brain is divided into sections that control different functions like memory, language, vision, and movement. The brain communicates with the body through cranial and spinal nerves. The peripheral nervous system connects the CNS to the rest of the body and is composed of the autonomic nervous system, which controls involuntary functions, and the sensory-somatic system, which transmits sensory and motor signals.

Overview ns
The nervous system is divided into the central nervous system (CNS; brain and spinal cord) and peripheral nervous system (PNS). The CNS is organized into the forebrain, brainstem, and cerebellum. It contains neurons and glial cells. The PNS connects the CNS to the body and is divided into somatic and autonomic divisions. It transmits signals between the CNS and peripheral organs.

The nervous system consists of the central nervous system (CNS) containing the brain and spinal cord, and the peripheral nervous system (PNS). The CNS receives sensory data from the PNS and controls the body, while the PNS is a network of nerves throughout the body. Neurons are the basic functional units and come in sensory, motor, and interneuron types. The brain is divided into the cerebrum, cerebellum, diencephalon, and brainstem. The spinal cord connects the brain to the rest of the body. The autonomic nervous system controls involuntary functions and is divided into sympathetic and parasympathetic divisions.

The brain is the central organ of the nervous system and controls many body functions. It is made up of several parts including the cerebrum, cerebellum, and brain stem. The cerebrum is divided into left and right hemispheres and is responsible for higher functions like thinking. The cerebellum coordinates movement and balance, while the brain stem regulates vital functions like breathing. The brain contains specialized areas for functions like sensory processing, memory, and emotions. Diseases can damage parts of the brain and disrupt related functions.
The nervous system anatomy
The nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord, which coordinate sensory input and motor output. The PNS has the somatic nervous system, which connects to skeletal muscles, and the autonomic nervous system, which regulates involuntary functions like breathing and digestion. Nerve cells called neurons are the basic building blocks and transmit electrical signals through structures like axons, dendrites, and synapses. The brain is divided into sections that control different functions like movement, senses, and higher thinking. The spinal cord relays signals between the brain and body. The PNS includes cranial and spinal nerves throughout the body
NERVOUS_SYSTEM.pptx
The nervous system consists of the central nervous system (brain and spinal cord) and the peripheral nervous system. The central nervous system receives and integrates sensory information and coordinates voluntary and involuntary motor activity. It is protected by three layers of meninges and nourished by a network of blood vessels. The peripheral nervous system comprises the cranial and spinal nerves along with their ganglia and sensory receptors throughout the body. It is divided into the somatic and autonomic nervous systems.

The document discusses the structures of the diencephalon, which includes the thalamus, hypothalamus, and epithalamus. The thalamus acts as a relay station for sensory and motor information to and from the cerebral cortex. The hypothalamus regulates autonomic functions like temperature, hunger, thirst, and emotional responses. It also controls the pituitary gland and circadian rhythms. The epithalamus is the posterior portion of the diencephalon.
