It also allowed us to use them to innovate and create tools. This resulted in the weight bearing function to be performed by the back limbs which created the unique lumbar curve of our spine. The lumbar curve gives us the ability to stand and even used lesser energy – walking on two feet uses 75% less oxygen. Creation vs. evolution: Australopithecine vertebra spinal cord spinal column lumbar One of the most overlooked areas of Australopithecine anatomy is the spinal column. Even if no skulls, pelvis', legs or knee joints were available for study, bipedalism in Australopithecines could have been established with this one area of their anatomy alone.
The normal curve of the lumbar spine in adult man is determined by maintenance of the trunk-thigh and the knee angles at approximately degrees. Alteration of this normal lumbar curve, either an increase in standing erect or a decrease in sitting or stooping, is caused largely by the limited length and consequent pull of the trunk-thigh. Loss of the Lumbar Curve in the Driving Seat. A Twenty Person Study. Reprinted & edited from British Osteopathic Journal Vol XIX pp , Abstract; The risk of herniated lumbar intervertebral disc is known to be high in drivers.
Page 40 - Then follow details of the indices of the lumbar verlebrae in the four man-like apes, as well as in nine of the lower apes. The statement that this curve is more marked in the female than in the male is strongly supported by the evidence adduced in this memoir, and it would seem that the vertebral bodies of the female are moulded more. This curve is termed a primary curve, which is Kyphotic. During the time the baby is learning to lift his head and eventually walk, muscles develop. As muscular strength and ability is gained, the baby’s activity will shift body weight to the spine. Gradually secondary curves develop in the cervical and lumbar regions; Lordotic curves. These.

Get this from a library. The lumbar curve in man and the apes: with an account of the topographical anatomy of the chimpanzee, orang-utan, and gibbon. [D J Cunningham]. WE are indebted to Prof. Cunningham, of Trinity College, Dublin, for a well-illustrated and exhaustive memoir on the subject of the lumbar curve in man and apes.
This memoir has been printed by. The lumbar curve in man and the apes, with an account of the topographical anatomy of the chimpanzee, orangutan, and gibbon.
The Lumbar Curve of the Spine. The lumbar curve was created by the psoas major when we came up to stand. As the psoas crossed the rim of the ischium and the pelvis rotated to bring the spine to vertical, the tone in the psoas pulled the lumbar vertebrae forward and the curve was created.
There are four curves in the spine, two go in and two. Lumbar Curve. Lumber Curve. SHUǏ SKINCARE. Travel Memory Foam Mattress Topper - for back support.

The lumbar curve is a permanent characteristic only of humans and their bipedal forebears, though a temporary lumbar curve appears in other primates in the sitting position. The cervical curve disappears in humans. A study published in Evolution and Human Behavior looks at the relationship between the angle of the female lumbar curvature and reported attractiveness from males.
This research was conducted at the University of Texas at Austin and was seeking to add to the discussion on what makes a mate physically attractive. The researchers recognized [ ]. If a client has a hyperlordotic lumbar spine, then because a lordotic curve is a curve of extension, it is important for the client to move into flexion and to create this motion at the lumbar spine.
Figure 9A demonstrates (therapist-assisted) double knee to chest stretch, which is an effective passive stretch into flexion to reverse a. This exercise improves the tone of the abdominal and lower back muscles, and it also teaches your how to relax the back of your neck. From Craig Williamson's book.
Understand Spinal Curves and How it Impacts Scoliosis Treatment. In short, with the loss of your spinal curve (normal spinal curves), your spine buckles under load. The reason why a spine would buckle when a curvature disappears from the neck involves physics.

Difference between Man and Ape. To trace the genealogy of modern man from ancestral monkeys onwards, fossils of ancestral apes have been thoroughly studied.
Man vs Ape. Vertebral column has two forward and the two backward curves; lumbar curve facilitates erect posture. Differences in Measurements of Lumbar Curvature Related to Gender and Low Back Pain Barbara J.
Norton, PT, PhD1 Shirley A. Sahrmann, PT, PhD, FAPTA2 Linda R. Van Dillen, PT, PhD3 Study Design: Cross-sectional. Objectives: To test the assumption that postural alignment and gender have a bearing on the specific type of low back pain (LBP) a person manifests.
The evolution of human bipedalism approximately four million years ago  has led to morphological alterations to the human skeleton including changes to the arrangement and size of the bones of the foot, hip size and shape, knee size, leg length, and the shape and orientation of the vertebral evolutionary factors that produced these changes have been the subject of several theories.
The normal curve of the lumbar spine is a lordosis. This is a forward curve that helps keep the discs and muscles in proper alignment.
The lumbar spine rests upon the sacrum. The place where they meet is called the lumbosacral joint, or L5-S1. The human spine has two distinct curves, a backward thoracic curve and a forward lumbar curve. This keeps the trunk and weight centered above the pelvis.
Chimp quadruped posture does dot require this shape. The lumbar spine is the lower back that begins below the last thoracic vertebra (T12) and ends at the top of the sacral spine, or sacrum (S1).
Most people have 5 lumbar levels (L1-L5), although it is not unusual to have 6. Each lumbar spinal level is numbered from top to bottom—L1 through L5, or L6.
The lowest part of the spine is known as a lumbar spine that consists of five vertebrae regions. The curvature of the lumbar spine is called lordotic curvature or lordosis. The amount of curvature in this region depends on person to person but the normal average range is 40 to 60 degrees.
The advantage of a greater lumbar curve and especially the more dorsal (backward) placement of the upper curve for females is their ability to more easily counter act the forward placement of the center of gravity during pregnancy, thus reducing the.

These five bones that have an anterior curve (inward) hold up the trunk transferring the weight of the head and shoulder to the pelvis and legs. The lumbar vertebrae are the some of the largest and heaviest vertebrae in the spine, second in size only to the sacrum.
A cylinder of bone known as the vertebral body makes up the majority of the lumbar vertebrae’s mass and bears most of the body’s weight. Posteriorly the body is connected to a thin ring of bone known as the arch.The normal spine has an S-shaped curve when viewed from the side.
This shape allows for an even distribution of weight and flexibility of movement. The spine curves in the following ways: The cervical spine curves slightly inward, sometimes described as a backward C-shape or lordotic curve The thoracic spine curves outward, forming a regular C-shape with the opening at the frontor a.
