Study Notes

Pudenal Nerve Block

Procedure for anesthetizing the pudendal nerve to alleviate pain in the pelvic region.

Femoral Triangle

Anatomical region in the upper thigh bordered by the inguinal ligament, sartorius, and adductor longus.
Contains the femoral nerve, artery, and vein enclosed in the femoral sheath.

Knee Joint Anatomy

Medial Meniscus: More susceptible to injury than the lateral meniscus.
Cruciate Ligaments: Provide anterior (ACL) and posterior (PCL) stability.
Medial Tibial Collateral Ligament: Represents a remnant of the adductor magnus muscle.
Lateral Fibular Collateral Ligament: Derived from the peroneus longus muscle.
Knee Mechanics:
- Locking: Quadriceps femoris, specifically vastus medialis, locks the knee at full extension.
- Unlocking: Popliteus muscle begins flexion by unlocking the knee joint.
Bursitis Conditions: "Clergyman's knee" refers to infrapatellar bursitis, while "Housemaid's knee" denotes prepatellar bursitis.
Terrible Triad: Common knee injury involving ACL, medial meniscus, and tibial collateral ligament.
Knee Capsule Innervation: Supplied by genicular branches of the obturator nerve.

Ankle and Foot Anatomy

Tarsal Bones: Eight bones forming the posterior part of the foot.
Ankle Joint Stability: Most stable in dorsiflexion position.
Spring Ligament: Also known as the plantar calcaneonavicular ligament; supports the head of the talus.

Nervous System and Nerve Supply

Tongue Innervation:
- Trigeminal nerve, facial nerve involved in taste and movement.
Hypoglossal Nerve: Responsible for tongue movements.
Vagus Nerve Functions: Several branches, including Arnold’s nerve (auricular branch) and Criminal nerve of Grassi (posterior gastric branch).

Muscle Innervation Overview

Larynx: All muscles except one are supplied by the recurrent laryngeal nerve.
Pharynx: All muscles supplied by vagus nerve except stylopharyngeus (glossopharyngeal) and tensor veli palatini (trigeminal).
Palate: Most muscles supplied by vagus nerve except tensor veli palatini (trigeminal).
Tongue: All muscles except palatoglossus (vagus).
Mastication: All muscles supplied by the mandibular division of the trigeminal nerve.

Anatomical Structures of the Neck

Carotid Sheath: Contains the common carotid artery, internal jugular vein, and vagus nerve.
Dural Venous Sinuses: Blood-filled spaces that collect venous blood.
Cavernous Sinus: An important structure that can induce pulsatile exophthalmos due to increased intracranial pressure.

Embryology

Developmental Phases: Pre-embryonic, embryonic, and fetal stages.
Gametogenesis: Includes spermatogenesis and oogenesis; specific locations and durations involved in each process.
Neurulation and NCC Derivatives: Critical in CNS development.
Gut Development:
- Includes foregut, midgut, and hindgut differentiation.
- Omphalocele refers to herniation at the umbilical ring.

Musculoskeletal Structure

Rotator Cuff: Group of muscles and tendons stabilizing the shoulder.
Scapular Anastomosis: Important for shoulder mobility and blood supply.

Lower Limb Anatomy

Lumbosacral Plexus: Key nerve links between lumbar and sacral plexus; known as nervi furcalis.
Major Nerves of the Lower Limb: Supply various muscle compartments including anterior, medial, and posterior compartments of the thigh and leg.
