The nervous system controls voluntary and involuntary movement through networks of neurons that send signals between different parts of the body. It consists mainly of bundles of long nerve fibers called neurons. There are three main types of neurons - sensory neurons that carry impulses from stimuli to the brain/spinal cord, connecting neurons that relay impulses between neurons in the brain and spinal cord, and motor neurons that carry impulses from the brain/spinal cord to muscles and glands to elicit responses. Each neuron has an axon, cell body, and dendrites that receive and propagate nerve impulses.

This document discusses the nervous system and endocrine system. It covers the following key points:
- Neurons are the basic building blocks of the nervous system and communicate via electrical and chemical signals. The nervous system uses neurons, neurotransmitters, and synapses to transmit signals throughout the body.
- The nervous system is divided into the central nervous system (brain and spinal cord) and peripheral nervous system (nerves connecting to the body). The peripheral nervous system has somatic and autonomic divisions.
- The endocrine system is another communication system in the body that uses hormones to regulate functions via the bloodstream, rather than electrical and chemical signals like the nervous system. Glands like the pituitary release hormones
Brenda and annabelle
The nervous system is formed of two main parts - the central nervous system and the peripheral nervous system. The central nervous system contains the brain and spinal cord, while the peripheral nervous system consists of nerves that connect the central nervous system to the rest of the body. Nerves transmit signals as electrical impulses between the brain and different parts of the body to coordinate voluntary and involuntary body functions. The nervous system also includes the autonomic nervous system which regulates involuntary body functions and responses.
Body control systems
The nervous system and endocrine system are the two major body control systems. The nervous system consists of tissues that conduct nerve impulses quickly, bringing about fast, short-term changes. It has a central nervous system of the brain and spinal cord, and a peripheral nervous system of all other nerves. The endocrine system consists of glands that produce chemical messages called hormones, which travel through the bloodstream more slowly and bring about long-term changes. The nervous system contains neurons that receive, transmit, and process sensory information and control motor responses through electrical and chemical signaling between neurons.

The document provides an overview of the nervous system, including its main functions and divisions. It discusses the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which branches out from the CNS. Within these systems are neurons, the main cell type, and neuroglia which support neuron function. The document outlines the structure of neurons and how nerve impulses are conducted. It also describes the divisions of the nervous system including somatic, autonomic, afferent and efferent systems.
Neurons brain edited
The document discusses the organization and functions of the nervous system and brain. It describes:
- The two major divisions of the nervous system are the central nervous system (CNS), comprising the brain and spinal cord, and the peripheral nervous system (PNS), connecting the CNS to the rest of the body.
- The CNS contains the brain and spinal cord. The brain is divided into the cerebrum, cerebellum and brain stem. The cerebrum is responsible for higher cognitive functions and is divided into four lobes.
- Neurons are the basic functional units of the nervous system. They communicate via electrical and chemical signals. When stimulated, neurons fire action potentials to transmit signals.
Nervous system
The document discusses the integration and control functions of the nervous and endocrine systems. It states that:
- The nervous and endocrine systems interact to control most body functions.
- The nervous system exerts rapid control via nerve impulses, while the endocrine system's effects are more prolonged and mediated by hormones.
- Both systems are communication systems that receive and deliver messages throughout the body.

nervous system
The document describes the structure and function of the nervous system. It can be divided into the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS). Neurons are the basic functional units that connect and transmit information via electrical and chemical signals. Communication between neurons occurs at synapses, where neurotransmitters are released to transmit signals between neurons. Reflex actions are automatic responses that occur quickly through defined neural pathways without conscious thought.

Nervous system
The nervous system is divided into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of the brain and spinal cord and integrates sensory information and initiates motor responses. The PNS consists of nerves outside the CNS and carries information between the CNS and body. Within neurons, an action potential is conducted down the axon when the membrane potential exceeds a threshold. At synapses, neurotransmitters are released by the presynaptic neuron and received by the postsynaptic neuron.

Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort. Histololgy of Female Reproductive System.pptx

Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

It consists mainly of nerves that are enclosed in bundles of long fibers called Neurons. Sensory Neurons -carry impulses towards the brain and spinal cord (responsi-ble for senses) -carries impulses from stimulus receptors Connecting Neurons -carry impulses from one neuron to another -only found in the spinal cords and the brain (central nerv-ous system) Motor Neurons -carry impulses away from the brain and spinal cord (central nervous system) to muscles and glands, then those carry out the response -most are stimulated by connecting neurons, by some are connected straight to sensory neurons 2 McKenna Chase Thursday, October 23, 2014 at 9:21:26 AM Pacific Daylight Time 70:cd:60:8b:aa:a6
