Basic Entomology - External Features of Insects
This document provides an overview of the course ZOO 305: Basic Entomology at Lagos State University. It discusses the definition and content of entomology as the study of insect biology, ecology, and importance. The course will cover the external features of insects including the head, thorax, abdomen, wings, and legs. It will also examine insect orders, ecology, population dynamics, and economic importance. The document uses the American cockroach as a model to describe insect morphology and external anatomy in detail over several pages.
Mosquitoes are insects belonging to the order diptera
Mosquitoes can be identified and categorized into 12 genera based on observable morphological characters. Four genera - Anopheles, Toxorhynchites, Uranotaenia, and Wyeomyia - have a single distinguishing characteristic not found in other genera. The remaining genera can be grouped based on whether the tip of the female abdomen is pointed or blunt, and whether the wing scales are broad or narrow. Observation of structures like the proboscis, palpi, antennae, thorax, legs, wings, and abdominal patterns allows differentiation of genera.
Insect head
The insect head contains openings for the mouthparts and prothorax. Mouthparts can be hypognathous, prognathous, or opisthognathous depending on the orientation of the head. The head also contains compound eyes, ocelli, and segmented antennae. There are six fused segments that make up the mouthparts: preantennal, antennal, labral, mandibular, maxillary, and labial. Mouthpart structure varies between insects and can be mandibulate, lapping/chewing, siphoning, sponging, or piercing-sucking depending on the insect's feeding habits. Antennae serve sensory functions and come in various shapes

It describes some key mammalian characteristics like hair, sweat glands, mammary glands, teeth structure and more. It then classifies mammals into two subclasses - Prototheria and Theria. Prototheria are described as egg-laying mammals found in Australia, while Theria are viviparous and divided further into Metatheria and Eutheria. Examples of orders within these groups are also provided.
Morphology of Cockroach | Dr.BGR Publications
The document summarizes the morphology and characteristics of cockroaches. Cockroaches have an elongated, dorsoventrally flattened body divided into three segments - the head, thorax, and abdomen. They have a pair of antennae that act as sensory organs, three pairs of legs, and two pairs of wings. Their mouthparts consist of labrum, mandibles, maxillae, labium, and hypopharynx. Cockroaches are nocturnal, omnivorous scavengers with compound eyes adapted for low light vision. Males and females differ in size, wing and abdomen shape, and presence of reproductive organs and anal styles.
Chapter_11_Study_of_Animal_Type_Cockroach.pptx
The document describes the external features, digestive system, and circulatory system of the earthworm Pheretima and the cockroach Periplaneta americana. Key details include:
- Pheretima is segmented with clitellar, pre-clitellar, and post-clitellar regions. It has setae, pores, and aphidures.
- The cockroach has a segmented body with head, thorax, and abdomen. It has compound eyes, antennae, wings, and three pairs of legs.
- Both have a digestive system including a mouth, alimentary canal, and anus. Pheretima's intestine has typhlosole
Entomology (Insect Parts)
The thorax is the middle body region of insects and contains three segments - the prothorax, mesothorax, and metathorax. Each segment contains a pair of legs and, in many adult insects, one or two pairs of wings. The thorax houses muscles that power the legs and wings. It is composed of rigid exoskeleton plates on the dorsal, ventral, and lateral sides of each segment. The thorax contains three pairs of legs and, in most adult insects, one or two pairs of wings that are adapted for functions like flight, protection, and sensory roles.
EMBRYOLOGY AND ANATOMY OF NASAL SINUSES.pptx
1. The document describes the anatomy and development of the paranasal sinuses, including the ethmoid, maxillary, sphenoid, and frontal sinuses.
2. It discusses the boundaries, landmarks, variations, and classifications of each sinus. For example, it notes the ethmoid sinus originates from invaginations in the fifth month of development, while the maxillary sinus is the first to develop in the third month.
3. The document provides detailed information on anatomical structures and variations that are important to consider during endoscopic sinus surgery, such as the location of the optic nerve in the sphenoid sinus and different types of frontal sinus cells.
Scalp and Face
The document describes the anatomy of the scalp, face, orbits, and nasal cavity. The scalp has 5 layers - skin, connective tissue, aponeurosis, loose connective tissue, and pericranium. The face is divided into 9 regions. The orbits have frontal, lateral, medial, orbital, and base bones. The nasal cavity has walls formed by maxilla, ethmoid, sphenoid, palatine, and lacrimal bones.

The document summarizes the life cycle of Schistosoma (blood fluke) parasites. It describes the adult male and female worms, including their sizes, locations of organs, and differences between S. haematobium and S. mansoni. It also describes the eggs produced by female worms, including sizes and key distinguishing characteristics. Additionally, it mentions the cercaria larval stage that forms in infected snails and has organs allowing penetration of human skin to continue the life cycle. The life cycle involves adult worms mating in human veins, females laying eggs, eggs passing in urine or stool to water where they infect snail intermediate hosts, and cercaria emerging from snails to penetrate human skin.

The document describes the morphological features of various parasites and their eggs, larvae, cysts, and adult forms:
1. Parasite eggs come in different shapes - spherical, oval, D-shaped, tray-like - and some have special features like spines or capsules.
2. Larval forms include cercariae that are biforked-tailed or have distinctive head and tail colors, and cysticercoids that may appear red or embryo-like.
3. Adult parasites include flukes that are leaf-like, tapeworm segments that are square or barrel-shaped, and filarial worms found in nodules with double uteri.

Plasmodium
This document discusses malaria and its causative parasite species Plasmodium. It identifies four Plasmodium species that cause malaria in humans: P. vivax, P. ovale, P. malariae, and P. falciparum. P. falciparum is shown to have multiple ring stages in its life cycle. The document was authored by Mohammed Abdelmoneim Abdelhamid from the Parasitology Department faculty of medicine at KFS university.
Toxoplasma gondii
Toxoplasma gondii is a parasite with a life cycle that involves rodents and cats. It has two stages - the tachyzoite stage where it is crescent-shaped and has a spherical nucleus at the broader end, and the oocyst stage where it is oval-shaped and contains sporocysts and sporozoites. The document provides details on the morphology, life cycle, and microscopic images of T. gondii.
Trypansoma cruzi
The document summarizes key morphological stages in the life cycle of American trypanosomes, including the epimastigote and trypomastigote stages. It also describes the physical features of the Triatoma bug, the insect vector that transmits trypanosomes, noting its size, coloration, segmented antennae, proboscis, wing structure, and abdominal segments.

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.

MERCURY GROUP.BHMS.MATERIA MEDICA.HOMOEOPATHY
Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.
