This is that part of the body which extends from the buttock to the foot. It is made up of the following region as arranged supero-inferiorly i) Guteal region ii) Hip joint iii) Thigh iv) Knee joint v) Leg vi) Ankle region vii) Foot region
Principally, the lower extremity consist of the following structure the skin; muscles; bones; neurovascular bundles which are the artery, vein and nerves. The spaces also found in the lower extremity which are located in designated planes include
1) Femoral triangle/Scarpar's trigone
2) Adductor's canal/ John Hunter's canal
3) Osteoaponeurotic openings
4) Popliteal fossa
LUMBOSACRAL PLEXUS | this is the collection of nerves that serves to mediate and to which provision of innervation to the lower extremity is anchored. In broad sense, there is actually two plexus merge together. Seperately the LUMBOSACRAL consists of
Lumbar plexus and Sacral plexus.

INTRODUCTION TO ANATOMY: TYPE AND TERMINOLOGY
Anatomy is an art and science that deals with the cutting off and disposition of body parts for proper understanding. Anatomy is being studied from various dimension, which include the following:
* Macroscopic anatomy | it is otherwise referred to as the gross anatomy with the use of specially prepared body known as cavader employed so that dissection is the order of the day.
* Microscopic anatomy | it is an approach that involves the use of microscope. The cellular makeup of an organ or tissue is being investigated, the absence of the approach is in the facts that different structures in the body are made up of different tissue.
* Developmental anatomy | it is an approach referred to as embryology. It tends to study the development of an individual from conception and after birth. Hence, a fully grown human being is natured at the age of 25. This is because the piriformis bone gets fully ossified at that age. It is against this backdrop that the development period is divided into prenatal and postnatal stage.
* Anatomy of the odd
| this is of main importance in the sense that it helps to solve many family dispute. Hence, this study dimension is known as THERATOLOGY.
Anatomy TERMINOLOGY
*anatomical position: this is a position whereby the body is placed on a couch in a supine position with the face placed upward, the two hands are placed by the side and palm directed forward.
*Superior sagital plane: this is a line drawn from the head (precisely from the centre of the frontal view to pubic symphsis) from the centre of the forehead downward to the level of the pubic symphsis such that it divide the body into symmetrical halves.
*Medial plane: the term medial refer to any structure placed towards the median plane.
*Lateral: structures that are located away from the trunk, farther from median plane.
*Inferior: simply refers to structures that is situated nearer the sole of the feet.
*Anterior: structured in front.
On regional bases, human body can be divided into various parts which include 1- lower limb 2- upper limb 3- trunk which are composed of three zones 4- thorax 5- abdomen 6- pelvis and perineum. Other regions of the body include the neck and the head.
