This document provides an overview of animal tissues. It begins by explaining how tissues fit into the organization of living organisms, from single cells to organs to organ systems. The major types of animal tissues - epithelial, connective, muscle and nervous tissue - are then introduced. The remainder of the document delves into various subtypes of these major tissues, describing their structures, locations in the body, and functions. Key tissue subtypes discussed include squamous, cuboidal, columnar and glandular epithelial tissues, areolar connective tissue, cardiac and skeletal muscle tissues, and neurons.

The muscle are biological motors which convert chemical energy into force and mechanical work.
This biological machinery is composed of proteins – which is actomyosin and the fuel is ATP.
With the use of muscles we are able to act on our environment.
On the basis of the function and occurrence ,tissues present in animal body is called animal tissue. These animal tissue is classified into the following four types:
Epithelial tissue

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

damaged, platelets
form a plug that seals
the vessel, and injured
tissues release
molecules that help
the clotting of blood.

65. NERVOUS TISSUE
Nervous tissue is composed of highly specialized nerve
cells called neurons and supporting cells or
neuroglia.
The neurons, which are the basic units of
communication, react to stimuli and transmit the
impulses (information) form one region of the body to
another.
Neurons extend throughout the body and do not act
alone.
66. STRUCTURE OF A NEURON
Neurons are usually long, large and complex in shape.
It consists of a cell body and several cytoplasmic
processes.
Processes that transmit impulses to the cell body are
dendrites and usually are multiple.
The single process that transmits impulses away forms
the cell body in the axon.
