Name the three muscles of anterior compartment of forearm and arm with its origin and Insertion

The anterior compartment of Arm contains 3 muscles:

1. the biceps brachii.
Origin: Short head: coracoid process of the scapula.


Long head: supraglenoid tubercle.
Insertion: Radial tuberosity and bicipital aponeurosis into deep fascia on medial part of forearm.

2. the brachialis
Origin: anterior surface of the humerus, particularly the distal half of this bone.
Insertion:coronoid process and the tuberosity of the ulna.


3. the coracobrachialis.
Origin: Coracoid process of scapula
Insertion: Anteromedial surface of humerus distal to crest of lesser tubercle









Three muscles of Anterior compartment (Forearm):


1. flexor carpi radialis
Origin :medial epicondyle of humerus (common flexor tendon)
Insertion :Bases of second and third metacarpal bones


2. Flexor carpi ulnaris muscle
Origin
Medial epicondyle (common flexor tendon) and medial margin on olecranon of ulna
Insertion
Pisiform, hook of the hamate, base of the fifth metacarpal bone


3. Flexor digitorum superficialis


Origin :medial epicondyle of the humerus (common flexor tendon) as well as parts of the radius and ulna.


Insertion :anterior margins on the base of the middle phalanges of the four fingers


What are the Parts of a Long Bone ?

What are the Parts of a Long Bone ?

A long bone has two parts: the diaphysis and the epiphysis. 
 
  1. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone.
  2. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled wit spongytubercle

Bony Component of the Wrist Joint


Bony Component of the Wrist Joint
 The wrist joint consists of two rows of carpal bones. The proximal row contains (from radius to ulna) the scaphoid, lunate, triquetral and pisiform bones, and the distal row the trapezium, trapezoid, capitate and hamate

Bony Component of ankle Joint

Bony Component of ankle Joint
 The bony architecture of the ankle consists of three bones: the tibia, the fibula, and the talus. The articular surface of the tibia may be referred to as the plafond (French for "ceiling"). The medial malleolus is a bony process extending distally off the medial tibia.

What type of Bone patella is ?

The patella, also known as the kneecap, is a flat, circular-triangular bone which articulates with the
femur (thigh bone) and covers and protects the anterior articular surface of the knee joint.

The patella is the largest sesamoid bone in the body.

Patella is flat, short and spongy sesamoid bone of knee joint.

Classify the synovial Joint with Example

Classify the synovial Joint with Example

 The six types of synovial joints are the 
  1. pivot, 
  2. hinge, 
  3. saddle, 
  4. plane, 
  5. condyloid 
  6. ball-and-socket joints.                   
The pivot joint, also known as rotary joint, allows for rotational movement. Pivot joints are indicated as joint letter A on our illustration. This type of joint can be found between your neck vertebrae. For instance, when you turn your head side-to-side, it's due to the rotary motion permissible in pivot joints.
Next, let's focus on hinge joints, shown as letter B on the diagram. Hinge joints are the synovial joint type referred to in our introductory section. These joints can be found between your upper and lower arm bones, otherwise called your elbow, as well as your ankles, fingers, toes, and knees.
Hinge joints operate just like the hinges on a door. They allow for a swinging motion, where bones can either flex toward one another or extend apart. Twisting or overextending a hinge joint can result in injury. If you've ever twisted your knee or rolled your ankle, it's likely that a hinge joint was forced to move in a manner it shouldn't have.
Saddle joints, indicated by letter C in our illustration, are similar to hinge joints but provide more range of motion. In the case of a saddle joint, the bone sitting on the saddle can move in an oval shape relative to the other bone. Our thumb is a classic example of a saddle joint in action. Thumbs can move using a hinge-like motion but can also rock side to side. This is because of a saddle joint. In fact, it's the saddle joint that makes our thumbs opposable, a trait that allows us to firmly grasp objects with our hands.
Plane joints, sometimes called gliding joints and shown as letter D on the diagram, are probably the most difficult joint type to visualize. They are usually associated with the small bones of your wrists and ankles. In this type of joint, bones slide along beside one another. This allows for movement in many directions, hence the flexibility of your wrists. Here is a picture highlighting the location and type of bones associated with plane joints in your wrist.

Next, we have the condyloid joints, indicated by letter E on our illustration. These joints form where the head of one or more bones fits  

Name the Movement of Hip Joint

Name the Movement of Hip Joint

The hip joint, scientifically referred to as the acetabulofemoral joint (art. coxae), is the joint between the femur and acetabulum of the pelvis and its primary function is to support the weight of the body in both static (e.g. standing) and dynamic (e.g. walking or running) postures.

The movements that can be carried out at the hip joint are listed below, along with the principle muscles responsible for each action: 
Flexion – iliopsoas, rectus femoris, sartorius, pectineus. 
Extension – gluteus maximus; semimembranosus, semitendinosus and biceps femoris (the hamstrings)

Name the bony component of Shoulder joint

Name the bony component of Shoulder joint

The shoulder is made up of three bones: the scapula (shoulder blade), clavicle (collarbone) and humerus (upper arm bone). ... Because the socket of the shoulder is shallow, the joint relies on surrounding soft tissues to support it and hold the components in place.

Define Spastic Gait

Define Spastic Gait

Spastic gait occurs when a person drags his or her feet while walking. This type can also make someone appear to be very stiff when walking.

 Spasticity is a condition in which certain muscles are continuously contracted. This contraction causes stiffness or tightness of the muscles and can interfere with normal movement, speech and gait. Spasticity is usually caused by damage to the portion of the brain or spinal cord that controls voluntary movement.

 

Define stance phase of Normal gait

Define stance phase of Normal gait

Stance Phase: The stance phase is that part of a gait cycle during which the foot remains in contact with the ground. For analyzing gait cycle one foot is taken as reference and the movements of the reference foot are studied. It constitutes 60 percent of the gait cycle.
